Add -target.id- on both leave and join variables. That gives the inviter id. Add -target.username- that gives the inviter username without pinging him.

There also some bugs with the vanity URL, thats gives errors on join and leave messages.

What is wrong with vanity URL?

[johntaxmi]

throw error when they join and leave sometimes, or when they join from vanity sometimes they say they joined from someone else, and same happens with leave
