If you could change the site in one way, how would you do it?

-- I would like to have it so if you see a "friend" on line you could say hello like a facebook poke - like when someone goes " on line " I think the only way you can do something like that is to send them a message saying hello - which take like a billion mouse clicks - then sending a message with just " Hi " in it seems lame - so then you are stuck adding something else - that requires so much thinking that it makes the thought of just saying hello too much of a bother -

I would make it so nobody can post text in the forums until they have offered at least ten image posts first.

Serious suggestion: i'd like to be able to have one click button to list the forum topics I have posted in, and be able to decide if I want to track them there or not. Likewise have the ability to change the tracked state from my home page.

 it's a very interesting how it would work i mean live chess tournament , there would be some number of group size or how it gonna be looks like???
