Hi! I took a long break from second life.... 6 years to be exact, I've made a new account and now I'm having problems with changing my appearance. I've forgotten about a lot of things and there have been so many changes. So, I've purchased shapes and skins and changing shape has worked out just fine but I can't get the avatar to change skins.... And I'm just a little lost.... I've tried reading blog posts but it's all so theoretical! Man, I thought I knew what I was doing... Can anyone help me, please?
