"Contribution2Use" system : to get access to SVN and timeline, you have to work. A precompiled pack is distributed, and allow any people who want to help to be part of the project. Read this FAQ for all needed informations.
"Anti-custom" policy : all configs which have been judged useless have been cleaned up. A big work on admin commands and panel has been made aswell. Users can apply patches shared on the forum 'Custom' section. The point is to give you the CHOICE about what YOU want to add on YOUR server.
"Quality > quantity" behavior : I test a lot of times before commit. If a share is dangerous for pack integrity, it is tested as long as it is needed.
