Fill your invite link once below, copy the description and tags, then work down the list — each button opens the site's submit page directly. Tick each off as you go; progress is saved on this device.
Before you start: every one of these sites requires you to log in with your own Discord account (OAuth) to claim a listing — that's a Discord security requirement, not something any tool can skip on your behalf. A few (Disboard, Disforge) verify ownership by asking you to post a short code in your own server. Budget ~25 min for the first full pass; after that it's just /bump on Disboard every couple of hours — add the Bump Reminder bot so members do that for you.
