I took 4 years of German in school, but that was many years past.  Ich kann jetzt nur ein bisschen deutsch sprechen.  Ich habe zu viel vergessen :(  Send me a message if you'd like to Skype chat.  

Also, one small correction - "We can teach each other" and not "We can teach us each other".

Your entry is reall quie good.  There are only a couple of very small errors.

My start on this site

I know it's not nice to get started here with a complaint but I'm really annoyed. I signed up yesterday and before I had even filled out my profile, I received follower requests from several people - only males, of course and most of them 20 years younger than me. Most of them neither study German nor speak any of my target languages as their mother tongue. None of them had ever written anything but two or three introductory sentences in their notebook - always in English although some claimed to study other languages, too. One of them stated to study German said/stated he studied German but didn't bother to write any a single German word when he sent his request. I've been through all that on other websites and perhaps I should just ignore it but I can't help wondering about how such people think. Don't they have sensible things to do in their life that they spend their time sending stupid messages to people or are they so desperate to start a relationship? Do they really expect an answer? Do they get any answers? I made some attempts on other websites to find out reasons by answering the messages of such people but not one of them replied. It often gives me the impression they don't even speak enough English to say more than "Hello, I want to talk you". But how should I talk to such a person when the first impression already gives me a clear sign that we have absolutely nothing in common. Since I turned 40 I use to I used to make my age public on websites like this, hoping it will prevent people from sending me such stupid messages. It obviously doesn't work - or perhaps younger women receive even more such spam. Just an especially ridiculous example: My profile says I'm looking for Skype exchange. This morning I received a message from a Turkish guy who wants me to add him on Skype. According to his profile he studies Russian - so does this make any sense? Are some people collecting contacts? I'm not and I'm interested in quality, not in quantity. Well, all this stupidness won't prevent me from using this site to improve my language skills and everyone who's interested in a true and productive language exchange is very welcome to get in touch, regardless of gender and age. Any corrections of this text are also very welcome.

In the first part, "stated he studied German" is the correct grammar.  "Any" is not exactly wrong, but it feels a little bit unnatural.  "I use/used to" is a common mistake that many native english speakers make, so don't feel bad about that one.  

Most of your entry is excellent.  Only a few small errors. :)

I will go to Australia...

I talked to my professor last week, because we had to choose the topic for my (Master's) Thesis, which I will start to write next year in April. I was very nervous before the conversation, because I knew that another decision had to be made at that day: WHERE to write my thesis. My professor (allows students to) write (Bachelor's or Master's) Thesis at other universities in foreign countries and I think this is a great opportunity to see other countries and people and it will help me to find a job later, because in Germany many companies require that you stayed some time in another country during your studies.
Before the conversation I thought my professor would send me to the US, because most of the students who write their (theses) at other universities go there. But as I entered the room he told me his idea was to send me to the University of South Australia in Adalaide. After the talk I felt uncertain. I did not expect him to send me to Australia! What should I expect from Australia? It is so far away... and it is winter when I will stay there April-July!
Now after some days I (am getting used to) the thought going to Australia, but I still think a lot about it. And the main problem will be to tell my parents about this...

It is most common to include a ('s) when saying Master's Thesis.  Saying your professor provides something is not exactly WRONG, but it sounds very unusual.  He allows you to do something is better and more commonly used.  Theses is the plural of thesis, and that sentences deals with plural students so they must have plural theses.  "I get familiar" is not really correct.  It would be better to say "I am getting used to".

Overall this was quite good and at a high level.
