I have to agree that we need a "clean" and easy to implement portal page. I'm sure that this will be the mod to have and there will be a lot of "modules" added as time goes on.
I have a third site that uses a Snitz board (It's a M$ .Net site in .asp) and it has a portal that users design modules for. It's a great addon, but I really feel that UBB is more flexible and will offer a lot more customization through the use of style templates and integration into the rest of the board.
One question though...with the code you guys are building now, will this easily integrate into sites with UBBs that are already hacked or are you aiming for a complete package that will be added as the rest of the hacks are on a clean install?
