[Inkscape-devel] [bug tracker] Guideslines for tags?

The new 'cloud' rendering of all tags on https://bugs.edge.launchpad.net/inkscape shows a total of 287 used tags. Are there any guidelines to follow when adding or renaming tags besides the visible 'official' and 'other' tags of the default interface on https://bugs.launchpad.net/inkscape?

Is there a more suitable place to ask/discuss questions like this about the bug tracker and bug triage?
