We currently have a and a . Overall, I think that united-nations is clearer, but UN has a wiki excerpt and more questions and followers. There are only three questions that are tagged with both, and I believe that one would be sufficient on those three.

I would like to copy the wiki and excerpt from UN to united-nations and then make UN as synonym for united-nations (such that UN will be replaced with united-nations). I have privileges enough to at least start those processes. I'm not sure what happens with the followers in that case, as I've never done it. I believe the questions get migrated.

My question is if there is any reason why I should not do that? Either to keep them separate or to go the other direction.

I copied the tag wiki and then merged the tag into using the mod interface. This should retag all the questions, create a tag synonym and also update any subscriptions.

No problem. A similar case was about the and tags, see details here.

I've been also subscribed to the RSS feed containing the former tag globally across the SE network, and I keep receiving notifications for Politics.SE questions tagged the latter one.
