How about overhauling the forums here? The header mis-matched colors have bugged me for the longest time and many other aspects of the theme. If possible it would be best to integrate the site with forums.
In terms of hosting/networking, I would suggest little change here. The network currently is fast and pages load in a zip. With that said, hopefully these speeds will remain consistent in upcoming years with the servers not getting packed to full capacity with many customers. (BIG mistake by my previous host.)
Oh..and something I suggested a while ago but I don't believe it was possible then, was integrating the helpdesk to your client area account. But I doubt that's still possible.
