Unfortunately, naming things is hard, and JujitsuHub just doesn't roll off the tongue the same way that GitHub does. jjhub? forgesu?

Dojo is such an obvious thing, but its such an obvious thing that there are dozens of software trying to call themselves that.

You just don't have to think about it too hard:

jjplace/jjhub/codetown, whatever. Doesn't matter.

Names don't matter that much for brands. Names just have to be simple enough to remember (ideally two syllables or less). What the heck does Nike mean, for example? Boeing is just someone's name. Microsoft is just two words smashed together. A brand's name literally doesn't matter.

you don't have to name your forge after the VCS it's based off of.

JitHub.

("Please don't sue us.")

JujutsuJunction (Ju³), obviously.
