I need a custom plugin for my self-hosted MeshCentral instance (running on Linux). The goal is simple: every user account should automatically deactivate on a date I pre-select, and I must be able to change that date at any time from the admin side. Key behaviour • When I create or edit a user, a date-picker field appears (ideally right inside the user’s account page). • On reaching the selected date, the account is disabled and the user can no longer log in. • A visible dashboard alert should start appearing for the admin seven days before expiry and remain until the account is disabled. No e-mail or other notification methods are needed. • Only the admin role needs access to set or edit the expiry date; regular users never see the picker. • The plugin must install cleanly on the current stable MeshCentral server running under Node.js on Linux, without breaking existing functionality. Deliverables 1. Complete plugin source code with clear inline comments. 2. Installation/upgrade instructions and a quick test script or steps so I can verify expiry works. 3. Brief readme explaining how to adjust the alert lead time if I wish to change it later. Please bid with your final, all-inclusive price—no adjustments after the bid is placed. PLEASE NOTE: YOUR BIDDING PRICE WILL BE CONSIDERED AS FINAL PRICE, NO NEGOTIATIONS WILL BE ENTERTAINED AFTER YOU PLACE YOUR BID.
