These are three boards that I think would be majorly helpful. Let me explain why:
Rants- If theres one solid board that people go too where they can rant (appropritely) it will cut back on some, if not all of the rants spread throughout CS Forums. Its a way for people to connect through experiance, and maybe get alittle help to make it through.
Raves- Something good happpened to you? AWESOME. I bet someone else wishes it happened to them. A joker? Finished your royal set? You know what? Congrats Man, you earned it. Cause everyone needs to showoff a little.
Wishlists- Tired of hunting through the Trades forum for the one pet you really want? If there all on one thread, the people with the pets can find YOU. Every user can have one board in this thread, and insted of a WANT thread, where people beg, its a Wishlist, so you can update it later when you've found something.
Just putting the ideas out there. Anyone like em'?
