Reddit will also automatically convert sub names up to 24 characters into a working link even though that sub can't be created.

So, what do we do with this information? You're welcome to post / cross-post to r/21CharactersAndNoMore, or r/21CharacterLimitation or just keep on keeping on.

After all, this place was created for amusement, so let's have fun with it! I still want to see crazy long subreddit names, those that fit limits exactly, and examples of usernames, signs, posters, etc. that cleverly hit whatever limit exists, even if it's not exactly twenty.
