what if you would like to consolidate your poems under different names into one author?

Write them all as one author. Simple solution. There's no need for multiple accounts unless you're so obsessed with hitting #1 that you need lots of tens which nobody else is going to give. If nentwined lets people move poems around users, there'll be people maxing out the 20 most recent from different accounts and then transferring them all to one. Which is stupid really, because anyone posting more than one, maybe two poems at a time has to be a really good writer otherwise nobody's going to bother reading more than one of them.
