Yes - first the purpose. Jim and I wrote up a list of possible purposes last spring. Jim? Do you still have that?
Capacity... well, disk space is pretty trivial. Time/programming is an issue. The Community Server is quite flexible, but it will take time to exploit it and that's the core.<grin> I would never try searching the Yahoo site for anything - it really has no structure to speak of. But that's the advantage of our model here - we have the capacity to have blogs (such as this), articles, uploads, forums, and so on.
Actually, the reason for the two step structure that our site has is the marketing/communications model. The front page is our calling card and should have a little more flash and be more static. We need to add a map of our location, replace the pictures I stuck on it with some better ones and write a stronger blurb.
You go through this to the Community Server which will get you the blogs and photos and such - a little more loose content structure.
Houston Camera Club. Nice enough. Basically static. I'm hoping we can do a lot more than that. A lot of those pages - the monthly meeting dates and such - we could easily put on "front page" section and still leave the dynamic content on the back.
OK, from here on, I would say it may be a little unclear about what Community Server does. This is an open ended platform with a SQL back end that supports forum structures, blogs, photo upload/displays/responses links to other blogs/forms and so on. It includes a quite detailed user database that supports user bios, photos, links to user's web sites and so on. All of the things you've talked about linking out to are native to the system. <grin> Even palate choices - you can choose your own color palate so it displays in a fashion that you like.
