My name is Eric.

I am a Mathematics student in ITB, Inodonesia.

I want to know more about mathematics especially outside of my country.

I want to ask question about this forum:

1. how can i close a thread started by me, (something like [SOLVED]). I've seen it somewhere, but don't know how to give it [SOLVED] mark.

2. How can I write tex notation?

3. Do this forum has rules?

4. What is a reputation? I've seen it in the bottom of a post, and i don't know what is it for.

Thank you so much
