Ah, right, that makes it clearer. The nick, alternative nick, name, and email settings currently have a number of characters stripped out, including colons, to make them safe to store in INI files, specifically the servers.ini, which needs to parse colons for some server parameters. However, it does look like only some of the servers.ini parameters need to have colons removed, so this issue will be fixed in the next version of mIRC.
