user1587: so i came across this question seeing retag and figure i create the tags. as i was about to add occultic-nine i noticed that occulticnine already existsed but must5 have been orphaned as there was no questions to it.
when i tried to create occultic-nine to match with other tages like steins-gate, chaos-head and robotics-notes which used the same naming structure as the others (Occultic;Nine, Steins;Gate, Chaos;Head, Robotics;Notes) i got this

I would like to request that occulticnine be made a synonym of occultic-nine so that occultic-nine is used instead.
Also i would like to know why i got this error. yes the error explains the problem however occulticnine had no questions to it (or atleast they weren't appearing when i searched the tag) so it shouldn't be giving me problems to begin with

Krazer fixed it. Hooray!
(He didn't make it a synonym, though. There's no point in having tags that differ only by hyphens be made synonyms of one another, since the tag autocompleter will find the tag either way.)

In revision 2 of the same question, Arcane created the tag [occulticnine]. The OP then changed it back to [retag], which is why no questions with [occulticnine] showed up in search for you. The zero-use-tag-deleter will get rid of [occulticnine] when it runs in a few hours, but for now [occulticnine] still lives.
