This is something I saw at another group today in their discussion of Yuku.
"I also joined two YUKU groups and discovered (after messing up) that if you anticipate belonging to more than one group register with up to five names(you can add a # after your pen name) and use each name for a spicific group. Otherwise you bring all your personal comments from one group to the other and there'll be a "tag" after your name indicating another group name. I'm told that is a NO NO!"
