I'm not sure what you mean by 'support', UltraFractal has one of the most active support communities around.  There is a very active (50+ messages a day) mailing list that you can join on the UF site as well as communities in Yahoo and dA.  There are many tutorials (the ones that are included in the Help section of the program are excellent by themselves!) and even classes at  the Visual Arts Acadamy online with Janet Parke and Kerry Mitchell, two people who have been involved with UF since it first appeared.  If you have any questions on any of these, or need more information you can send me a site mail.
