That said, I know your question was about how to combine all of your 3 blogs into one account.
You say
How do I put all of my blogs under one account? I do not understand half of the instructions on your site. It is not very 'non-tech' friendly. :) Please make it simple.
I don't know what your 3 accounts are, but I'll try to explain how to transfer two of them into your main account, without being too technical.
Please make it simple. Thanks!
Here is the support article about transferring one blog (account) to another:
http://en.support.wordpress.com/moving-a-blog/#transferring-your-blog-to-another-user-or-account
Choose which account / name you want to have for all three.
I'll call it "A " to be your ultimate choice for your main blog.
You also have blogs I'll call "B" and "C."
Notice: Each blog / account / name ("A," "B," and "C") has an email address stuck to it. That is why you have to keep signing in and out to access your different blogs.
You have a different email address for each blog: WordPress.com thinks you are three different people because each email address is how they identify who you are. To them, you are three different people "A," "B," and "C," because each of those blogs has a unique email address. Like psuedonymns. It (wp.com) doesn't know you are the same person.
What you need to do, in order to combine all of your accounts is to have persons "B" and "C" transfer their accounts to your main account "A."
