bug #898 priority questions (Was "Re: Timeframe for 1.4")

From: Ted Stern <dodecatheon_at_gmail.com>
Date: 2006-02-08 22:14:31 CET

Hello all,

I'm interested in the status of bug #898. My organization will
likewise wait for it to be dealt with (1.4 or later) before converting
from CVS to svn, unfortunately.

- How do I find out whether someone has been assigned to the bug?

- Bug #898 has 52 votes. How do I see how that compares to other open
  bugs?

Ted
