# What to do with unnecessary tags?

I've found some information on the meta about merging tags by proposing synonyms, but what about the case where the asker of a question creates a tag whose necessity is debatable? If this does overlap with the content of a previous thread I'd appreciate a link (I looked and couldn't find one)

The example that made me think of this is here, where the tag twin has been created. This tag isn't really statistical and will most likely never be used again. I suppose it could be merged with something like multivariate or clustered. In looking at the list of tags, there are many other examples like this. What is the recommended action here?

• Another option would be to rename it [twin-study] and add the tag to questions like this: stats.stackexchange.com/questions/24155/… May 22 '12 at 4:02
• or just merge it with the [genetics] tag... May 22 '12 at 4:03
