Any Suggestions!?!

Hey everyone. If I have ever desired a comment in my comment box from you, the time is now. School is about to start once again in a few weeks over here in the Czech Republic, and I was curious to know if any of you had any fun ideas about activities or topics that would be fun to go over (it can be beginner level or advanced). Anyways, just thought I'd throw that out at you all. Just give me something to play off of, a fun topic, an interesting idea. Anything will be awesome. thanks.
