Okay it works.
As for the $comnet, I'm not sure exactly what you're looking for. Do you want it to take a nickname and return common networks based on nicks which you can see (ie. that you share at least one channels with on a network) or do you want it to actually check if that nick exists anywhere on that network (if so, it won't be possible to write an identifier that does that).
The 1st one. And thanks for the code.
