email already registered

email already registered

(my apologies to the moderator i have reposted this under another account just five minutes ago, but i thought since i will be using this forum i should create an intended-to-be-used account and write in a piece of paper this time my user name and pass. another apology for posting this in getting started but i couldn't find a support section)

i tried creating an account with my standard email and got a message that my email is already registered.
my emails are all safe, so i suppose its a false alarm, or probably i have registered with a zoho account somewhere and i cant seem to remember when , where and why??
any info on the topic would be much appreciated

thank you in advance
