Register for the Jurism support list to receive project announcements and post support queries. The list is currently hosted on a Mailman server at the university where I work. Sometime in the next year or so (before I retire from the day job on April 1st 2022), I’ll be moving subscriptions, with member consent, to an external forum.
As noted in the Documentation: Jurism client page, the Zotero forums are also a valuable source of information, but the Zotero developers cannot be expected to respond to queries related to Jurism.
Sign up for (or visit your account on) the Jurism support list.
