The domain name "rootdb.com" makes it sound like the site is about databases. That's not a topic that I find particularly interesting, so I would have assumed that it's not for me from the start and probably would not have gone there.
I'm not a big fan of the organization of the site. When I first looked there, it was a jumble of miscellaneous topics. It wasn't even clear to me that it was a "forum" in the sense that I'm used to. (Still isn't, to be honest, but I probably missed something). Clicking on the forum link takes me to a search form. Since I'm new and not looking to search for anything, that isn't really helpful to me. I could be misunderstanding the purpose of this site, so forgive me if this is not a helpful thing, but what I'd love to see is the ability to browse by section with the posts in reverse chronological order. Being able to turn off the thumbnail images would be a bonus.

I wouldn't unless I found myself using the site pretty frequently for a while first. Registration is a very big ask and I won't do it unless there's a very big reason to.
