Intel Mac :: Created 2 IClouds / Can't Access Either One?

I had set up my iCloud account, but for some reason, it didn't follow through. So, after resetting my mac ID, I set up another iCloud account. But every time I try to access it, and type in my Email addy, it says my email address is already taken that's absurd, since I had already created it! It suggests others,that I don't want to use! What's the deal here with not allowing the Email addy I choose before? I finally put in a number at the end, & it went through.Now I "supposedly" have 2 accounts - But, I'd like to get rid of one of them - the second.The reason is, that ever since I created that second iCloud account, (it shows up on my Email inbox), I still can't access it.

Second, when I tried to access this support group, it automatically has my email address, but it kept saying my Password is wrong, when I've used this password for my mac stuff, since 2006, when I got my first mac. Finally, I put in my "num de plum" & was able to get in to do this one.I am still unable to access it. How & where is it on the computer? The only place I can find anything about iCloud is in Systems Preferences. 

Third - I did "goof" by listing my new iMac (the '06 one crashed) as 10.4.7, when it is 10.7.4 - So Sorry, but I am dyslexic & dyscalcula! Some fella said I should "amend my signature" in a rather demeaning way. (I've been using computers since dos - 1991)I have now done that. But he also suggested "I understand you had a MobileMe account and have migrated it? If so, go to System Preferences>iCloud and sign out. Now sign back in with your @me.com address.I've never had a "MobleMe" account. The only account I had was an iMac account, ca. 2006, but never renewed.SO I guess that won't work. What will?  I am still unable to access or find it. How & where is iCloud on the computer? The only place I can find anything about iCloud is in Systems Preferences. going to a new OS, that is very different than your old one, even if it's mac to mac, is no easy trip.
