Email addresses as IDs?
I may be wrong, but I seem to notice an alarmingly increasing number of new participants who chose their email addresses as Adobe IDs. Apart from the carelessness, this is likely to produce problems in the topic lists of these forums, and I know I have raised the point before. If I remember correctly, I was told that rules on ID format were dictated in the adobe.com site, where they don't care about such trifles. Pity. If it's not Jive, it's Adobe.
