A Website that enumerates your manga or anime you've seen/currently on?

Help finding out what its called, maybe leave a link to it? I know it ain't animenews network, (or is it?)

I think I've seen some people's sigs with the link that goes to a visitors preview of their account directed to that site.

It enumerated list of manga/anime you have the pleasure of, or just briefly scanned, or even hated reading/watching.

I just wanna make an account, (condition if free of course, hehe) so i can keep track of manga/anime i've seen and so i can go back to them again in the future (updated for new chapts). I'd just lose it if i write it on a piece of paper or word doc, *sigh*.

I've got a lot, and i mean A LOT of saved bookmark tabs to the various manga/anime sites but i keep losing track coz some chapter updates take so looong (and i forget their titles T_T).

And even if i develop some kinda amnesia, i'd just go to the site! (considering i also don't forget my username/password) lol.

Arigatou to ye submitted answers!
