Took me a while but since slime do's not want the PA I have chosen topbadges as the winner of the prize the rain effect was kinda of cheating but a very nice effect and was a good use of filters Topbadge please supply your steam id here and the server you wish to have it on and I will sort the rest.
Would is make you feel better to know how to add your own rain? http://www.photoshopessentials.com/photo-effects/rain/
