can't use email add as password
hello, just got a new macmini with mavericks pre-installed. I have been using Macs for years and already have an apple id account. when trying to set up icloud with my email address, or trying to change my username to my email address, it tells me the address is used already. I have found I have two accounts, the one I am aware of and use for iTunes etc. and another that was last used in 2006 for Applecare Confluence Wiki. i
I can't remember what this is for. I have changed the password for the old account, but can't see away to delete or merge the two accounts. any info on how to proceed? thanks
macbook 13, mini mac, Mac OS X (10.4.8)
