I personally think this topic was more of a convenience/log more than anything
I mean, if you have nicknames, usually there something special made up by the person who made it up. In other words, as long as certain people use that special nickname, there really isn't a need for a list. ...Especially when some of the names are more jokes than nicknames :x And the people who made the names will always remember them and use them :3
Besides, if there's a name you want to be called other than your username, you can always say something like "KL is fine"
...Most definitely the biggest thing though is that this topic is pretty much dead :v
