Nice idea and script. Have you allowed for things like netsplits (where services go down) and folks rejoin on mass to find they all change by default to a fixed "Default1234" nick ?
It was more of an observation more than anything.. alot of clients dont use auto-id .. and on netsplits or if services go down.. its an all too familiar sight lol .. en-mass nick change to server default
somehow hawkee wont allow changes to posts i wanted to update it but i get weird replies about adding code while code is there and already posted
but its a good thing to think about the netsplit scenario
