I really hate when people on msn talk in 1337. I was hoping it was possible to either have a filter that will either filter it to something like "User is usinng 1337" or change it to normal english.
Translation...
It might a little diffitcult because of the plugin for MSG plus that leets every message and letter like i am doing right now. You are going to have to like find out all the caracters of every letter that is leeted the filter it.
If they are using l33t speech in Messenger it's possible they're using a plugin, like StuffPlug's auto-talker. If that's the case I guess it would be easier to translate it. In the message above, it looks like each letter is replaced by the same character.
