Mike, are you working on the changes at http://www.xenunity.com/? When going to XFHost.net and then clicking on the Community link it gives a 404 error.
Correct other then our billing software, I will be moving WHMCS to microcart in the future but Michael is still working on cPanel features for me to do so.
I think you should keep the current theme and approach. Having a support forum inherits the look and feel of the WHM theme. Judging by the mockups It looks unprofessional. Anyway thats what I think... Best of luck.
