Atrixware is a provider of a wide variety of eLearning solutions. They just recently purchased HelpSpot and have really gone to town on portal customizations as you’ll see below. They also were able to get me kick started on a script I’ve wanted to write for a long time. In their old support desk they used phpBB and wanted to transfer the old discussions to HelpSpot’s forums. This lead to the development of the phpBB_to_HelpSpot script now available in the hacks section of the documentation.
They’re also hosted by the good guys over at ValiantHost.
