I won't be able to make this skin because I can't extract the resources from the bloody skin dll (they aren't stored as normal resources that can be viewed in ResHack or whatever, and I have no idea how they are stored).
If anybody can install it and figure it out (I assume they are stored in "C:\Users\<name>\AppData\Local\Yahoo!\Messenger for Vista\Yahoo.Messenger.Skins.YmDefault.dll"), I shall be happy to continue working on the skin, but I just can't be bothered making all of the resources from scratch
