I just checked and I've registered 82 people again for this month (on the 30th). This has been my average for the past 4 years. I get about 3 new members every day, every month.
And besides that I still have dozens of "guests" online that don't register and just come to read the forum.
My purpose is to show that my UBB forum is still viable and still very attractive to our members. Of course, I keep it alive by changing the header graphic almost every week, and I have some neat Islands that are dynamic.
You can see it at
http://vcca.org/forumAlso, I have a bunch of "members only" forums restricted to actual club members.
I think that the product is still very strong. My suggestion is to create a whole new "library" or "store" where we can share all kinds of add-on's to it. Sort of like what was done with themes... but different. Realize that once you add a modified theme -- then you're pretty much done.
What this new "library/store" needs to do is to list a ton of different products (like Islands) that people would want to modify/personalize and add to their site... Then they'd want to add another one... and another one....
