Export from your current tracker
Trackers like InviteLogger have an export command that hands you a JSON file of every member's counts. That file is all E.N.D needs, no API keys, no permissions on the old bot.
Your invite counts come with you
Months of invite contests are data worth keeping. E.N.D reads the export file your current tracker already produces, and every member keeps their count.
Run /invites import with the file
Attach the file to the command, pick merge (keeps the higher count, safe to re-run) or replace, confirm with a button. The import shows how many members it found before it writes anything.
From then on, the registry never forgets
E.N.D keeps two things apart on purpose: a permanent record of who invited whom, and resettable counters for the leaderboard. Staff can reset a contest to zero as often as they like, and the history survives every reset.
What you gain on the way
Join announcements naming the inviter, real/left/fake breakdowns, staff bonuses, role rewards at invite milestones, an invite leaderboard tab, and a dashboard pane with the whole board readable at a glance.
One honest note: exports carry totals, never who invited whom, so imported credit lands as bonus and the detailed breakdown rebuilds from real joins going forward.
