UPDATE 18 Sept. 09:44 UTC:
Issue now resolved, sign up system now fully functional
17 Sept 14:41 UTC
It appears we unfortunately have a small service interruption in the sign up system. You can still continue to sign up for the JOTA-JOTI event. The system will send you a confirmation email with your JID code. And you can edit your info with the link provided. All your data is ok.
However, your entry will not appear immediately in the list of registered groups. We are working to resolve it soonest. No need to resubmit your info.
