Did you guys find something which does that? I want to do this for my enhancements as well.

Actually I was thinking that an option would be to use the Live Feed functionality, especially now after it's pumped up in Fuji.

You can follow a record(enhancement), invite members,   teams, create very quick Polls with custom questions (pretty much like an enhancement-internal survey) in which people can vote (if you have created the voting questions). I think it's kind of handy.

Only downside is that LiveFeed itself does have a lot of stuff in it - many menus, many options, many places to look and it could be a bit confusing.

Anyway, as for me, if I don't find anything easier I will probably try to run that.

Cheers!
