We currently have a un and a united-nations. 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.
