Comment 2 for bug 50425

I think this is a bug rather than an RFE. <https://launchpad.net/distros/ubuntu/+spec/winmodem-support> was mistakenly not scheduled at all for UDS -- because one person marked himself as drafter, and another subscriber marked him-/her-self as essential, but neither of them attended.

Perhaps participation should be per-sprint and separated from subscription. (Also worth considering is whether VoIP can be counted as participation without attendance.)
