Funambol has a very big community with lots of people that contributed to the project over its many years of life. Its legacy is vast, made of 3 mailing lists spread in 2 SourceForge projects and one Yahoo! Group, one main project on OW2, many other contributed projects in the most disparate places (SF, GCode, self hosted), web pages of the free/libre version on the .com site and much more. All this deserves to be in one place. In a binary world things should be easy: move from point A to point B, delete duplicates and you’re done. But real life is harder because of one commandment of community management:
thou shalt not upset your community members
Changing a website can be very upsetting. You must give your users a good reason to change because it’s not just a matter of updating bookmarks. Your community members will have to register into a new system, change their habits, learn a new user interface, adapt their email filters.
I believe that the new discussion services on Collabnet are a fairly good reason, as will be the use of subversion (expected in July). Be delicate, be gentle and involve your community in the process.
