I love postnuke and I was a very active member over there. I also went through a few versions of the DuskyBlue system all the way up to the latest Envolution. The Xaraya project (if it ever happens) may be an awesome template engine but the focus seems to have been lost when the big postnuke split happened. It was ugly.
There are so many systems out there, and most of them have so many functions that most people don't need that they're turning into bloatware. e107 is a very thin system and runs well on most any virtual host.
When I built my personal site I went through literally 50 different systems before deciding to use pMachine. It's a blogging system on steroids. I don't need forums on that site and I turned off registration because it doesn't need member functions.

I think my needs for a UBB portal are nowhere near the typical CMS. I would like to have a dynamic "homepage" (calendar, latest threads, blah blah blah) and user/group level access to the site based on the UBB members files. I've seen pages done by LK in the past that were near perfect and I'm sure that something like this would be easy for a guru like him or CC. I know that I could learn it myself given time but I have a 9 month project start in a matter of days that coincides with a new server product that is going gold in 51 days. I just want to be the typical UBB user that opens up an editor and installs the great stuff that the devs here produce. This is the kind of thing that will help keep the UBB community alive.
