"Looking for clarification... A Facebook like button? How would this Like button work?"
It's a standard vBulletin feature Jim. IIRC I changed the "like" button to "thanks" but I don't think both can co-exist.
Need to have - RSVP, Thanks, Back to Top,
Tapatalk - this was bad in the past, allowing easy access for hacking. I’s imagine that’s changed by now but I’m not sure.
Member photo album - standard VB IIRC
Random Photos From Member Album - above yellow box - I liked it for visual interest but it’s high maintenance as lots of the pics are from people long gone. Probably delete that.
Starting over would lose too much good stuff IMHO
The DB shouldn't have any problems rolling to whatever version you want (except going backwards)
Going to the DB directly and removing junk is easy enough but keeping forums/ posts, members is pretty important.
This version has a lot of "features" not being used - articles, blogs, etc.
