FYI - AIESEC International got into EU-funded project that will include development of social/business networking tools of the likes of friendster.com, linkedin.com, itsnotwhatyouknow.com, etc. AIESEC is using OpenACS for its www.aiesec.net 100.000+ members system and is developing OpenACS-based system for alumni. Developments should start in autumn 2004. Unless Commission changes its opinion on the project, of course :)
Would be interesting to follow on this discussion to ensure that code developed in not too-AIESEC specific [or accommodates requirements of other potential users, to put it in other way].
