How do i intergrate a forum on one of zymics free templates? If i can what do i use?

the question should be, how do i integrate one of zymic's template on a forum.

It really depends which forum you are going to use, phpBB, invision boards.. i mean, there is a long list of forums.. and each one of them are different, and including designs is a LOT different from a forum to an other.

I personaly know how to do it with phpbb, but thats it...
