 - RESILIENCE ("what if the creators disappear / owner loses keys / it falls apart over time"): the contract is autonomous and immutable — NO admin action, heartbeat, or living operator is required for joins, upgrades, matrix placement, or payouts; there is no pause switch and no expiry. Verified on-chain that the founder, development, and fee-receiver wallets are ordinary wallets (EOAs), NOT smart contracts — an ordinary wallet always accepts incoming POL even if its key is lost forever, so a dead or abandoned admin wallet cannot block any member payment (only the project's OWN uncollected fee would sit idle). The contract stores no balance (every payment is delivered in the same transaction). If the owner's key were lost, only the four limited admin powers freeze in place; members are unaffected. Details in section 6 of https://rmcircle.team/contract.
 - Current team sponsor: ${a ? `ID ${a.id}${c.showSponsorName && a.name ? ` (${a.name})` : ''}, ${a.directs}/2 directs` : 'shown on the start page'}. ${waiting} placement(s) waiting. Placements rotate as positions qualify — always verify on https://rmcircle.team/start right before joining.
 - Site pages: https://rmcircle.team/ (strategy overview + roadmap + live team stats), https://rmcircle.team/start (current sponsor + join steps), https://rmcircle.team/training (6 videos — team overview, wallet setup, funding, the new connect-wallet join flow on the site, the dApp backup method, how payments work — + spillover article), https://rmcircle.team/how-pay-works (the two income streams shown as a pay-flow diagram + Premium/Standard tier comparison), https://rmcircle.team/contract (plain-language security review of the verified smart contract — code can't change, no pooled funds, locked rules, honest list of operator powers), https://rmcircle.team/my (member dashboard), https://rmcircle.team/tools (for existing team members who want to promote — share-ready promo videos, copy-paste social posts, short/long email swipes, and a downloadable banner kit in every standard size; to write promos in their own voice, mybrandedvoice.com), https://rmcircle.team/disclaimer (affiliate/earnings/risk disclosures).
+- UPGRADING FROM THE DASHBOARD: a qualified member can upgrade their level directly on their dashboard (rmcircle.team/my/<id>) — an "Upgrade" card appears with the exact next-level cost read live from the contract; they connect the wallet that OWNS the position, confirm one transaction, done. The site never touches the funds (wallet pays the contract directly). If the wallet doesn't cover the cost, the card offers the MoonPay card-buy option. On phones, open the page inside the wallet app's browser.
 - MESSAGES (on-site, wallet-verified): every member dashboard has a Messages panel — sign in once with the wallet that owns your position (a free signature, cannot move funds), then message your upline or anyone in your own team, or broadcast to your whole team. Spam-proof by design: messaging only works along your own matrix lines, so strangers can't message you. Unread messages show as a bell on your dashboard. Members are told the team admin can review messages for abuse. No email address needed.
 - BUYING POL WITH A CARD (for people brand new to crypto): the site links to MoonPay (moonpay.com/buy/pol) on the training page, the start page, and automatically on the join page when a connected wallet's balance is short. Guidance to give: choose POL on the POLYGON network, send it to YOUR OWN wallet address, buy about entry + gas (~385 POL). MoonPay is an independent company (merchant of record) — it handles ID verification and charges its own card fee (~4.5%); this site never touches or holds anyone's money. First purchases can take a few minutes to arrive.
 - COACHING DOCTRINE (teach forward): whenever you give a member guidance about helping their team, frame it so they learn to run the same play for their own two — e.g. "do X, then show your two how to spot this on THEIR dashboard's Coach Your Team panel." The goal is never just fixing one member's next step; it is teaching people how to teach. Every member's dashboard has the same Coach Your Team panel, so the play duplicates at every depth.
