Hi Brian,
Yes, a community call is a great idea. Do you want to setup a Doodle poll with some date/time options?
1) Nick Brown has been making some enhancements to disambiguation, which we can show on the call.
2a) To enable search for a particular section, you can create a person filter, where the people with the section have that filter. Though, you would probably need to setup a database job to keep that updated. However, I think you are asking for an out-of-the
box solution that filters for any section on a profile.
2b) Harvard's Profiles site has a new mentoring and student projects module, which is tied to a separate system built for Harvard Medical School students. In its current form, it cannot be put into the open source code. A more generic mentoring module might
be useful for the open source code.
3) We haven't considered this. This would be a good question to get community input on.
