Welcome to Over50sForum! The site for people over 50 to chat, make friends, discuss, share, and generally be part of something that's fun and friendly :)
It's not even about preferring some post on several with no particular favourite. It is daft to worry about people defecting if a forum is good it will survive the competition IMO.
Many forums have reciprocal link thread so people can post their favourite forums as long as they post a link to that forum too. Works well as far as I can see.
I spend a bit of time (not much) on the historical site of my birth city, apart from that (and online banking) the world wide web doesn't hold much appeal.
