v2.0 — Paid Tournaments, Ratings 2.0, and a Whole Lot More - Paid Tournaments: Verified organizers can now charge entry fees. Register with credit or debit card. Money is held safely by Acework until the tournament date, so refunds always work. - Full Refund Window: Cancel your registration up to 48h before the tournament for a 100% refund. - Organizer Application: Anyone can apply to become a tournament organizer — upload ID, sign the agreement, wait for admin review. - Primary / Entry Leagues: Tournaments and matches now split into Primary League (3.0+) and Entry League (under 3.0). Cleaner competition, better matchmaking. - Rating Overhaul: Refined ELO with match-closeness, per-set scoring, and stricter caps. Losing to a much lower-rated opponent finally hurts. - Club Matches v2: Both captains pick lineups in parallel. Lineup can be edited any time before the whole match locks. New "Free-form" score entry mode for informal sessions. - Shareable Cards: One tap to generate a beautiful share card for tournament finals, club match results, and profiles — with a scannable QR code back to acework. - Rules Page: Full rating algorithm + tournament format explained in plain English & 中文. - Push Notifications: Get notified when someone joins your tournament, pickup, or club match. - Countless UX polish: faster club/tournament detail pages, better error messages, admin tools, and dozens of bug fixes. Note: some paid tournament features require organizer approval — free tournaments, pickups, and clubs remain completely free for everyone.
