Changing Yourself?

[ArianZg]

I'm very new to this site,but I did find some very interesting things.As I searched a bit,I found the warlock pet skins addon.It was very cool,but since I'm not a warlock it was of no use to me.Then I got the idea that something could be done on your char.If it was possible to du something like that on a pet,it should be also be able on a player.I am a litle bored with my troll,so i thought it could be replaced with the Yarr! priate or noggerfogger skeleton model.Since I don't no anything about .lua,I would like if anybody of you professionals do it,or at least tell me it's not possible.

NOTE:My english is not anywhere near perfect,so please don't hate my for my sppeling mistakes
