Issues on fogbugz have 3 global states: 1. OPENED 2. RESOLVED 3. CLOSED OPENED: - add description - reported issue => add a slice information and put the issue on RESOLVED RESOLVED: - workneeded / review needed / fix to include after that the issue might be closed by the integrators On 2013-04-26, at 11:46, Pavel Krivanek <pavel.krivanek(a)gmail.com> wrote: > can we assign more tags to one issue?
