You’ve seen how many forums there are for Mozilla and Netscape, right? Including developer forums, there’s no way a normal human being can keep up, let alone participate. And so, I’m going on a forum diet.
Most notably, I’m no longer participating in netscape.mozilla.user.win32.
I don’t have the time to participate in netscape.public.general, or alt.netscape. I did some support in the UFAQ forums, but not anymore.
I started doing Netscape support in alt.netscape, so I’m still hesitant about leaving that one. 
In which newsgroups am I still giving tech support?
netscape.mozilla.firefox
netscape.mozilla.thunderbird
netscape.mozilla.user.general
netscape.netscape7.windows
The only web-based forums I’m going to do support in (on occasion) is Mozillazine’s Thunderbird and Seamonkey support forums.
