Add expertise level to each talk/event

[microft]

This year I really missed having information about if a talk was beginner/intermediate/expert level.

Anyone else think this is a relevant feature?

I've looked into the XML data and it seems not be be included there. Anyone know who I can talk to about getting it added?

The XML format probably won't evolve as long as Pentabarf is being used. The audience level could be included in the description text.
