I was interested in the specifics of a lifetime membership. However, when I click on the lifetime membership page, it just tells me that I am already a premium member. The only other option is to downgrade my account. Has anyone else found more specifics for the lifetime membership?

I tried to obtain a lifetime membership to get me started here and I get all the way to the visa check page. Entered my information, hit submit, and it tells me I need to enter a value in the name field. I had put a '.' after my middle initial so I cleared that, hit submit and all the fields went blank. I didn't bother entering any info on that page again. Should I have?
