Well, I met my husband through TSR, so that's a pretty significant start! We had quite a few TSRians at our wedding.
I've met 50+ TSRians over the years, predominantly through mod meets but a few subs' meets too. I have a reasonable number on facebook and am in regular contact with probably about 10.
Are the mods meets actually productive or do you just discuss ways you can further oppress us peasants?
I don't know what they're like these days as I stood down years ago, suspect a lot more corporate speak and a lot less booze. The business ones were usually pretty useful.
