Necromunda Campaign Tracker
Getting started
Four steps from a link in the group chat to a gang sitting in a campaign. It takes about ten minutes, and one of those steps is waiting for somebody else.
Every screenshot below is this app actually running. They are captures of a throwaway demo roster — the gangs and players in them are invented.
Sign up, then wait
Anyone with the link can register. You will be asked for your name, an email, your Discord name and your MundaManager name. Discord is optional — the group is on WhatsApp — but the other three matter: the email is how you sign in, and the MundaManager name is how the arbitrator matches you to a roster they may already be tracking.
Registering does not let you in. Every new account has to be approved by an arbitrator, so there is a wait between signing up and being able to sign in. You will be emailed when it happens. If nothing arrives within a day, chase it in the group — a missed approval looks exactly like a forgotten one.

Found your gang
Once you are in, Home is empty and the form to found a gang is sitting on it. Give the gang a name, pick the edition and your house or faction, and set your starting credits — 1000 is the usual founding budget, but your arbitrator may have said otherwise for this campaign.
Pick the edition carefully. N26 is Necromunda: Skirmish and is what current campaigns use; N23 is there for legacy rosters. The choice changes which rules the app applies to your gang, and it is not a cosmetic label.

Build the roster — Leader first
A new gang starts empty and tells you so: “A gang must include one model with the Leader Subtype.” Use Add fighter on the bar at the top to recruit. Start with your Leader — some fighters only become available once you have one, and a Leader joining generates Gang Tactics for the gang.
While the roster is still being built it shows as Founding, and creation-time choices stay open — alignment, alliances, corruption, and any options a fighter's card offers at recruitment, such as a Delaque leader's psyker option. Those options disappear once you submit the roster, which is the point of the Submit roster button: it says the gang is finished.

Get into the campaign
A finished gang is not automatically in anything. The campaign bar says so plainly: “Not in a campaign — ask your arbitrator to add it to theirs.”
That is what Message arbitrator in the sidebar is for. It goes to whoever runs your campaign, and they can reply straight to it — the reply lands in your inbox, not a no-reply void. Say which gang you have built and which campaign you want to join.
This step is deliberately manual. There is no self-service join button yet, so nothing happens until you ask. A gang can sit finished and unnoticed indefinitely if you assume the arbitrator has seen it.

If something looks wrong
Use Message arbitrator. It is the same button for a rules question, a gang in the wrong campaign, or a number that does not match what you played. It is quicker than the group chat, and it arrives attached to your account, so whoever answers can see what you are looking at.
Forgotten your password? The sign-in screen can send you a reset link — you do not need an arbitrator for that one.
