There was an original forum here in the UK which was started by a national company for the elderly somewhere around late 90s/early 2000, which was very popular. Started as a closed (private) forum and was ace.
Sadly, when it went global (not private), that's when trouble started - cue the racists, homophobes and anti-Semitic posters - couple that with new lousy mods who were little Hitlers in disguise, it went downhill fast. It closed down because of those posters stirring it, which was widely reported in the media.
After it's closure it spawned loads of new over 50 sites by ex-members. Some private, some not, some still thriving, some closed for various reasons including one recently (Buzz).
But back to the OP - yes, I've met many from forums I've been a member of. On one, I started a meet up thread for canal boating freaks like myself, which progressed well - barbeques, pubs ... it was fun with a capital 'F'

And there were those I didn't meet but gelled with where we swapped phone numbers or e-mails. Had a relationship with one chap, been witness for a couple who met and married off a forum and so much more - lots of many good memories from those times, along with the sad and bloody awful times.
Couple of fond memories I'd like to share...one chap I met in the boaters thread era, was a chartered surveyor. Great SOH, had a penchant for flirtyness which I loved to slap him down for. Good banter between us. He was a dreamboat to have in my back pocket - I moved a few times then and he did the surveys on the 'next property'. Never accepted payment, but I insisted treating him to a meal out as thanks.
Shopping in town one day, I noticed a bloke and recognised him from the his profile pic. He was older than me and his posts were such fun, chirpy, upbeat. Such a hoot and came across as such a great guy.
And there he was looking at underpants - so me being me, I went up to him and said 'Jimbo!'. His face was a picture - such confusion at this strange woman calling his name.

Cutting it short - he lived 10mins from me, widower with grandkids and his family were just as barmy as he was. We often went for drink or pub grub, days out etc.
I'm still a member of some sites, but not active. It's interesting that some sites still hark back to the good old days of that first site - even those sh*t stirring members are still spouting and getting suspended or banned, who go on to other sites and behave for a while and the cycle restarts until they get found out and banned or suspended. Never fathomed out how people get round the system of rejoining
I don't want to replicate any those days I'm just happy moseying along in here, dropping in now and again, and reading what's happening in other folks' lives outside of the UK.
