post = this little thing I'm doing now (this reply) thread = the little thing you just did (a main topic with a group of replies) forum = a whole GROUP of threads pertaining to a particular general topic (like basses, setup, electronics...etc...) you will not be creating any forum... you can create a thread (in fact, you did) capisce? welcome...
