In a kind of meme that you post in your journal:
The rules goes like this:
1. You must post these rules.
2. Each tagged person must post 10 things about themselves on their journal.
3. You have to choose and tag 10 people and post their icons on the same journal.
4. Go to their pages and tell them you tagged them.
5. No tag backs
You dont need to do it if you dont feel like it
