The decision to include an application in 4PSA Integrator is based on quality and popularity. Only the most representative and useful applications have been chosen.The selected programs are weblog engines, CMS, project management systems, usually collaborative software.
Among the useful programs, I have tried Joomla (CMS), phpCollab (project), phpBB (forums) or typo3 (CMS). B2Evolution and Life Type seems nice blog engines. There are surely other gems to discover.
