Let's see,best? This whole Gordon Lightfoot site.
Not counting the short lived little rants that directed at people I thought were being mean,it's been great here and still is.
Also,the M*A*S*H online/www.Joe Hollywood.com board. Nice folks there too.
When I had my home PC,chatting with fellow "naturists" was great too.
Worst?
On a "very" un-official Mariah Carey site,letting myself get drawn into a verbal battle of wits with,obviously,younger people.
They were just there to post nothing but negative & nasty things about her.
That was back in 2000 though and thankfully that site was deserted by it's owner.
Believe it or not as much as I talk about Mariah,I am not a member of any site about her. It's enough just to like her & her music. (but not her movies! :D LOL! )
