I like the idea of having skins for Messenger Plus!, I never talked about it much but the software is designed for it, you just have to put your XML files in the Interface directory. If you have some particular problems, just send me an email at mplus@patchou.com (if nobody else can help you the forum, I'm not very fast in replying my mails these days, I have just too many).
Keep on going
. If you do something good and complete, send it to me and I'll put it on msgpluslive.net
