Is anyone a member of memolink.com ?

I was going thru my email this morning and I have been noticing I have been getting a lot of emails from this site call memolink. I was think that it was just junk mail so i would delete the emails that they sent. Apparently I have an account there but I don't remember even signing up for this site. It looks like it may be a legit nice site to add to my favorites but I wanted to see if anyone else was a member of this site and could give me more information about it.
