@Bluepower10: You can add your own by typing it in the second box on the Add Server dialog (File > Add Server). The first box is for the default servers list, so if you don't have that, it should be empty, which doesn't matter as it adds the server from the second box (when you select something from the first box, it will be automatically copied to the second one)

@Aucun50: it should work perfectly without restarthing the dialog or even mIRC.

Edit: I've edited the description on the Add Server dialog. I think it should be clear now ;) If not, let me know
