Hi,
I am not sure, but I think Progress has nothing to do with this site (someone correct me if I am wrong please)....
But what does it matter? In my experience (in Europe) the people out there using the product know more of and about Progress than the Progress people themselves. Try the European Helpdesk if you feel like having some "fun". It'll take them on average at least 4 days and lots of emails before they even begin to understand your question (let alone give you an answer)... But anyway, that's besides the point.
Besides ProgressTalk.com there is also
www.peg.com (also not Progress owned/moderated I think). The Peg is more a mailing list. You can subscribe to several lists and questions/answers arrive in your mailbox (if you do not subscribe to a list you can read the posts via the website)... You can of course also post questions/answers, again via email. Depending on the list(s) you subscribe to the amount of emails you will get each day varies from hardly any to lots (look for instance on
www.peg.com/lists/peg/web to get an idea of what's going on there).
And then there is the "newsgroup".... comp.databases.progress. I have tried that a couple of times, but it's not really worth your while to even look there.
