I know it is weird to be moving Iris..if we don't like yuku we can always go somewhere else..I joined Moe's sharing group at both aimoo and yuku, and I don't see that much difference really..as for your nick, I don't about that..you may need to put a 1 after it or something..I've never come accross anyone else with your nick before..
Hope your Mom's Birthday is nice..good that everyone is pitching in to help her out..
