The Lightweight skin with Holiday themes! This skin fully colorizes with your Messengers background color and doesn't touch any menu icons or status images. Set the Holiday theme(s) of your choice automatically, use a manual theme or no theme at all.

Current Holiday themes available are: New Year, Valentines, St. Patricks, Easter (Western and Eastern!), Halloween, Thanksgiving (US and Canada dates) and Christmas.
Additional manual themes: Birthday, Celebration, Love

Don't worry about the dates. This version contains the correct dates for 2011 and 2012 and you will be notified about new releases (with new dates) automatically.
If you have a version older than 1.30 installed, you may want to uninstall it before installing this version (to prevent leftovers from the old).
