Merhaba!

Hi!
This is my first note and I feel kinda nervous I guess. I have really bad grammar. I don't know how I can make it better but I'll try to do it. If you can tell me where I'm wrong I'll be so glad. Because I think I can learn faster that way.
I want to use this "note" part like blogging. I can write about how I (feel?) through the day or if something happened, I don't know. It'll be fun for me ^^

Hi! You've only made a few minor mistakes! I understand what you're getting at in general! :) don't worry about it!

Merhaba!

If you want to improve your grammar, Aycan, start by resisting the temptation to write like a blog or a text message.

Your notes will be easier to review if they don't need to be interpreted first!
