@Improv I generated this invite from the contest channel and it should go right to it but they can be finicky. If it just plunks you back in the Isle, look along the left sidebar menu. There is a list of channels under various categories (the categories can be collapsed or dropped down) and the category you're looking for is Sharing Shores. The channel listed under it is contest-links. I'm going to ping you from that room as well, so you should get a notification and by clicking on the notification you magically teleport to the correct channel as well.

Safe travels!
