The existing tag Wiki for the flags-flag refers to the Flag (without s) module. While the existing tag Excerpt for this tag seems to not really correspond to that. For more details, refer to these (recently rejected) tag edit suggestions, in which I at first was trying to make it all related to the 'Flag' module:
Even though I can perfectly understand (now) the rejection reason, it appears to me as at least "not consistent", and something should be done to fix this (popular) tag.
It seems there are possibly 3 approaches (at least, maybe there are others ...):
- Create a new tag 'Flag', dedicated to the Flag module, and leave the 'Flags' tag as is (probably with a corrected tag wiki+excerpt to clarify the difference between both tags). Together with this, perform a mass retag operation from questions currently flagged with "Flags" to "Flag" (i.e. any question that is specific to the "flag" module).
- Create a new tag 'flag', together with marking 'flags' as a synonym.
- A moderator simply renames that tag from 'flags' to 'flag'.
Either approach could work for me, though "I'd vote for option 1".
