Uh.. why not just use JIRA?
fixVersion, status=Blocker, and Assignees are there for a reason...

I'm maintaining a small spreadsheet of issues  we need to resolve for
RC2. It is essentially a finer grained copy of what we have in Jira at
RYA-184  (in order to keep track of merges and whatnot).
If anyone is interested in working on RC2, check RYA-184 or this
spreadsheet for an open issue and ping the dev list letting us know that
you're on it.
