I tried to suggest the existing tag unity-game-engine (6 questions) as a tag synonym for unity3d (> 1000 questions). Although I have create tag synonyms privilege I run into the following error:
Failed to propose synonym:
Version specific synonyms can only be created by moderators
It sounds to me like the 3d in unity3d is considered as version number. Actually it stands for 3-dimensional. Am I missing something? Maybe version specific tags should rather have a flag set, indicating their special status instead of being recognised by a regular expression only. Or at least the check should be restricted to the end of the tag's name e.g. "[0-9]$".
There is a similar question Version Specific Tag Validation on Tag Synonym Page, I set up a new one as a moderator explicitly asked for it.
lmeras a synonym forlme4: stackoverflow.com/tags/lme4/synonymswifitag which is the same as802.11- not sure why I go the same error as Kay did when I tried to propose tag synonym in SO - thanks
