> So that anyone with an opneid can login
This includes this list,
http://openid.net/get/
Almost everyone has got one. If not, they can get one very easily.
i guess it include all openID provider including
yahoo,gmail,wordpress, and all major provider?
that will be great.
Trac has a few advantages, it can make it easier to keep track of
things than mail.
I would say a trac with openid and private ticket plugin will be a
perfect solution.
some results from Trac,fpo are visible to search engine(google) so
private ticket plugin protect it from search engine? even the e-mail
ofcourse. though email is not directly search able from google but
relaven search return the e-mail.
