--- Comment #10 from Olivier F. R. Dierick o.dierick@piezo-forte.be --- (In reply to Rosanne DiMesio from comment #9)
The general policy here is to avoid custom patches to bugzilla, as they would have to be rebased and reapplied every time bugzilla is updated.
The patch in comment 7 is to be sent upstream. If they do accept it, the only change required to WineHQ bugzilla is to remove the 'disable' file from the MoreBugURL extension to enable it. This will allow WineHQ forum thread links (and a few other trackers too but that's not a problem) in the 'See Also' field.
A custom Forum Thread field could simply be added through the admin interface as a custom free text field. Links would not be clickable, but that doesn't seem to have been a problem with the Staged Patchset field, which was created that way.
The patch in comment 6 is for that. It makes a to-be-added custom field cf_forum_thread a URL field just like the Staged Patchset field.
I think the best approach would be to try to send the patch for the MoreBugURL extension first, and if it's not accepted upstream, then go the custom field way.
