I think the confusion is coming from your use of the abbreviation "WLM"

WLM is generally taken to mean Windows Live Messenger, not Windows Live Mail.

Skins for WL Messenger already exist (as you are aware), but seeing as Messenger Plus! Live is only for WL Messenger, it isn't possible to have these kind of skins applied to WL Mail.

Perhaps consider changing the topic title, as you risk confusing a lot of people and getting answers stating that skins for WLM can be downloaded from the skins database, etc
