Yes, BBS and forum mean the same thing.

BBS or forum for setting up a forum?

The explanation I found on the Internet: BBS = Bulletin Board System (electronic) bulletin board, which means a place where information is posted.
Forum, discussion meeting, is a place to discuss some topics.
-前者强调个人性的活动；后者强调集体性活动，更科学一些。

PS: Testing the forum program and opening speed of the forum just after establishing it. https://www.wangmi.net/forum/
How fast is everyone's opening speed?
