# How do I change one tag to another (a slightly different one)?

I've accidentally created a new tag (or so it seems): vertex-buffer while posting a question. Then in another question I needed a tag about index buffer so I tried index-buffer and found out that index-buffers (plural) already existed. So I used that one.

Then I thought - both tags should be consistent - either both plural or both singural. So I wanted to change my vertex-buffer in the first question to vertex-buffers but I couldn't because it was similar to already existing... well, vertex-buffer (the very one I was trying to change!). So I couldn't. Couldn't use the plural vertex-buffers in the new question for the same reason.

Please, tell me how I can make them consistent or do that for me.

I merged all tags of vertex-buffers into vertex-buffer and all tags of index-buffers into index-buffer. Originally I did the opposite, but it looks like the majority of our master tags are singular in nature.

The merge destination tags were not otherwise used, so I didn't create a synonym; this was a one-time merge.

• I'm not sure if this counts as an answer but this whole topic is not about questions and answers, really. :P – NPS Aug 25 '13 at 21:06
• I suppose what I meant to be implicit in my "answer" was that you can't do what you were asking for directly (it requires either a certain reputation gate to propose synonyms or a moderator to merge tags). You could have waited a while and I think the unused tag would fall out of the system, but I'm not sure. :) – Josh Aug 25 '13 at 23:27
• @JoshPetrie There's a script that destroys "zombie tags" (tags with no questions) once per day, at 3:00 AM, IIRC. – Doorknob Sep 3 '13 at 0:28

To solve your problem, can't you remove the tag, save, edit again and add the similar one?

More general, I think questions with tags which are synonyms should be automatically replaced by one of those synonyms, for consistency.

I am not sure if a server side workaround exists, but otherwise you wouldn't get all questions of contentual one tag, but only of one specific synonym in the search results.

• Nice idea but unfortunately it doesn't work. Even when a tag isn't used at all, it still persists in the system. – NPS Aug 25 '13 at 16:50
• Ahh, so the issue is that a similar tag already exists in the system. Then this might be part of a moderator's job. But I don't know how to contact one for this subject. – danijar Aug 25 '13 at 16:53
