Help me to correct it, please.
Thank you in advance.

For your “About Me” tab:

First of all, I want to say that I’m sorry about my English. I don't speak it well. But I hope you understand what I'm writing here.

I’m looking for people who want to learn Russian, and who speak English or German fluently.
We can suggest different topics that interest us, and prepare ourselves for our talk.
If we spent about 20 minutes to an hour each day, we could help each other a lot.

As a programmer, I'm a bit of an introvert, so I don't put my color photo or a detailed profile on social networks.

We could speak on Skype or simply by text. In addition, if you are coming to visit Russia (St. Petersburg), we could meet in person.

For your “Activities tab”:

I'm here to learn English and German. Will help you with Russian in return. Feel free to ask any questions you may have.
