Welcome to the forum.
I've found that a good way to get a feel for what's in it is to use the "New Posts" button below the title bar after logging in. You get all the posts that have been made in all the sub-forums since your last visit.
For a while, I concentrated on those sub-forums of specific interest to a Georgetown Class C owner, but since we're retired from the RV scene now, I use "New Posts" every time.
