See Atomcal in action: seats and reserves on one calendar

The race and the reserve queue live on the same calendar. When someone drops, the next driver already knows the time.

Quick Architecture: How Reserve-to-Grid Auto-Promotion Works

AUTONOMOUS DISCORD LOGIC

Atomcal automates driver turnover using a 4-step event-driven lifecycle that converts waitlist entries into active racers instantly:

1. Timestamped Waitlist Entry: Drivers join with microsecond precision order, optionally weighted by Championship Tier or license standing.
2. Automated Vacancy Trigger: An active driver marking Absent instantly unlocks the allocated car seat without admin intervention.
3. Timed Priority Offer Window: Reserve #1 receives a Discord ping + DM with a strict 5-minute countdown before auto-cascading to Reserve #2.
4. Instant Role & Grid Sync: Upon acceptance, the driver receives @Active Racer permissions and the live lobby code.
The Grid Scramble Dilemma

Eliminate Vacant Grid Slots &
Unfair Reserve Disputes

When a confirmed driver withdraws 20 minutes before lights out, manual Discord messaging leads to bias accusations, missed pings, and incomplete 17-car grids.

✕ Manual DM sprints to check who is available on short notice.
✕ Subjective seat allocation causing reserve driver frustration.
✕ Unanswered Discord tags delaying lobby start times and stream broadcasts.

Engine Architecture

The 3 Pillars of Autonomous Grid Allocation

Engineered purely to eliminate empty grid slots and administrative friction on race night.

01

Timestamped & Tier-Weighted Queuing

Reserves join with microsecond timestamps. Configure pure FIFO or weight by Discord roles (e.g., Tier 1 Reserves over Academy Drivers) to respect driver rankings.

[QUEUE] #1 down1375 (Tier 1 Priority)
02

Cascading Dropout Escalation

When an assigned seat is forfeited, Atomcal initiates an automated claim countdown. If the candidate fails to confirm within the window, the offer instantly cascades to Reserve #2.

[TIMEOUT] No response in 5m → Pinging #2
03

Instant Role & Session Sync

Accepted reserves immediately receive driver voice permissions, the lobby code, and active roster roles while the public embed updates for commentators and stewards.

Trusted by Premier 20-Car Sim Racing Leagues

★★★★★

"We run 4 tiers of F1 racing every Sunday. Replacing dropouts used to cause 10-minute lobby delays. With Atomcal's 5-minute cascading claim timers, every single tier launches on time with a full 20-car grid."

Marcus V. Head Steward, Apex Racing Championship
★★★★★

"The priority queue eliminated reserve driver grievances completely. Drivers can see their exact position in the waitlist and know the offer is 100% fair and automated."

Dmitri K. Community Director, International Sim Series
★★★★★

"Role weighting was the missing link. Our official reserve drivers get first priority before general community substitutes, all handled by Discord webhooks without touching Google Sheets."

Direct Answers

Grid Allocation & Waitlist FAQ

How does Atomcal determine reserve priority order? ▼
Atomcal captures sign-up microsecond timestamps for pure FIFO (First-In, First-Out) queuing. Alternatively, organizers can configure Discord role weighting so designated Tier Reserves or Super License holders automatically take precedence over general members.
Can we weight waitlists by driver license or points standing? ▼
Yes. You can assign priority hierarchy to specific Discord roles (e.g., @Tier 1 Reserve > @Academy Driver > @Unverified). Atomcal evaluates role weight first, then uses timestamps as a tiebreaker.
What happens if Reserve #1 misses the claim countdown window? ▼
If Reserve #1 does not click "Accept Seat" within your configured window (typically 3 to 10 minutes), the bot automatically revokes the pending invite and immediately offers the car to Reserve #2 via public mention and DM.
Does Atomcal automatically update lobby permissions and car assignments? ▼
Yes. Once a reserve claims an open seat, Atomcal grants the @Active Racer role, provides private access to the lobby password channel, and assigns their name to the vacated constructor chassis on the live event roster.
