Anyone can share a filter with everyone else on FogBugz, just click Cases > Manage Filters…. Then check the Shared checkbox next to the filter you’d like to share. Or, if you’re using FogBugz Ocelot, you can just drag any filter you have saved down to the Shared Filters group.
The filter will then appear in all users’ Filter dropdown. Please note that the Shared Filters group is considered a filter group in the drop-down list. Shared filters can be hidden. Shared filters cannot be moved to a different filter group. If a filter is moved to a different group it will no longer be shared.
If you just need to share a one-off filter, click on the “More” menu on the right-hand side of the filter bar and select “Permalink” and then share this long link with your fellow users.
