MrStormyNights and Painfool -- In regards to the color problems -- have ya tried setting up a style template specifically for the application forms? If not, give it a try. If this doesn't fix your problem, please provide a url to the page showing incorrect colors, and i'll check out the problem.
I did infact use the Standard Style - that is how I discovered that by changing the "Table Border" color I could affect the Applicant Form background color. I have changed all the colors and was unable to ever change the actual table background used when posting a message via the application.
