Dear Piedad
1. We have a release manager (Joel Aufrecht).
We also have a number of people who advise in different areas. Check the list of advisors:
http://www.dotlrn.org/about/leadership/ and
the board of directors:
http://www.dotlrn.org/about/board/2. (I do not know about MIT's use of Ilias)
3. According to our CVS records 15 developers have contributed code reccently (http://cia.navi.cx/stats/project/OpenACS) but I think that the real number of developers is at least 3 times larger since most people contribute code in other ways and then this is commited by one of these 15. According to this web site we post new code every 2 hours while the well know Mono (open source implementation of .NET) project has a posting every 33min, only 4 times larger.
The release manager and core developers normally try to meet online every week. You are welcome to join us in the next one.
cheers
Rafael
