Any way to quickly switch between sites?

As far as I can tell there’s a way to quickly jump to the different Mediocre site forums via the Community option in the nav bar at the top, but is there a similar way to switch to the homepage of those sites? Basically if I’m on meh.com and trying to go to casemates.com, I can’t see a way to currently do that via the navigation without going to Community->Casemates to go to the Casemates forum, and then click on the Casemates logo at the top to actually get to casemates.com.

On a semi-related note, is there any plan to unify the account/login across Medicore sites so you don’t have to separately login on each domain?
