in order to use autoinvite you need to be logged in with a pnick.
Try to convince new players to use something called a comunit where you have to enter cryptic commands every time they want to log in. It doesn't work.
We tried this when "The Horde" was alive. We've noticed that a lot of the players were just unable to set up irc, even com unit was too much for them.
The game need accessible communication tools. Else every new player will ask you "Why don't you use Skype?" which I heard about 50 times at horde.
Besides I am giving you direct feedback from our ex members which were mostly new to the game. I'm not telling you stories
