I was a Froosher. I only paid to access it because it felt like a cool way to throw some money at the site. Fwoosh was free and I was there all the damn time. So I could throw them a few bucks AND get access to more forum as a bonus. Like the other guys - I don't think I was ever asked to re-up for it. I paid once and kept my Froosh status the entire time I was there.
There was certainly a little bit of shit-talking, but the big guys were pretty clear that you should talk on Froosh with the understanding that anyone can choose to become a member at any time; so don't say shit behind their back that you wouldn't say to their face. I -think- we all pretty much kept to that.
We did also have the rule that whatever got said on Froosh was supposed to stay there. Which MOST of us kept to. Primarily, I think, that was in case you did talk shit about someone - someone else wouldn't run to the public board and cause a whole thing out of it. But I never got the impression anyone really had any interest in doing that anyway.
As was said, it was mostly just more toy and life talk. Mostly the kind of stuff we talk about on AT here in threads like the 'Quitting Collecting' or 'AT Pets thread' and shit like that. Stuff that didn't really have a place in the public forum and/or you didn't really want to be generally public information but you were cool to share with like 20-30 other toy collector guys you talk to all the time.
