I like the idea that you're working on to make it easier to send a message to multiple people but just a few points:
The buddy list seems to have gone awol... this was a great way of ensuring that you'd managed to spell the nicks correctly. If we have to do 15 lots of cutting and pasting to create a clan list each time that is going to be a real pain. I suppose we could have a list stored externally but that isn't exactly user friendly.
What would be great would be the ability to create one or more groups of addresses that would be stored ready for us to use for multiple messaging.
