a few things
 

ive been looking but i can seem to find what im looking for .a few questions r what r the flames on the threads for??or what does it mean when ur subscribed mean??or how does a thread become sticky??

I think the flamed threads mean closed threads.
Subscribed to a thread means you are informed a post is made in that thread when one is posted.
A thread becomes sticked if it is SUPREMELY important.

And nice use of the chat speak :innocent

the flames on threads are for "hot" threads...they have reached a certain amount of posts, i think it's 15.

nevermind...I think that hot topics might have to do with views and not posts...

A closed thread will have a little "lock" on it.

when you subscribe to a thread, everytime you go into your user CP, the thread will be there, showing you if there was any new posts or not, basically what norrel said.

you can see what the symbols of the threads mean at the bottom of each individial board, there is a key to the symbols.
