I just stumbled across this website while doing some research. Has anyone else used it before?

I just stumbled across this website while doing some research. Has anyone else used it before?

It was a simple process of signing up for a free account (of course, premium services are also available) in order to access trees of other members. So far, I have found a large amount of information that pertains to my family line. It takes a while to learn your way around, but it seems easy enough to use. I haven’t yet done so, but you are also able to share your family tree with other genealogists.

Any comments would be appreciated, especially from those who have used this site before.
