I know it's not a huge hassle to login into Nickserve and then login to Des...but I'm frightfully lazy!
So, at the risk of repeating what others may have already said (doesn't think so, but it never hurts to get your apologies out in front!) the following might be useful for mIRC users.
Go to the menu at the top and then:
Tools, Options, Options, Perform (it's a box on the right) then type in to the blank box:
/msg NickServ IDENTIFY password
/join #lonely_inn_ooc
.msg Desdaemona !login password Nick
..and *boom*. Next time you open mIRC...you're logged in and straight in the OOC.
Hope this might be of some use.
<edit>
Small point, it's not Nick you use in the !login command, but rather it is character name; which you only need if your IRC nick and character name do not match exactly.
