I added a new feature to the TRACK OPTIMZER, so that groups of friends and communities can use the new group feature. The page "Do you already have Scalextric track?" screen now has a third option, [b]"We are a group / community". [/b]The user entering the data on behalf of his friends serves as the admin of the group. Data is only saved in the admins browser cache, not in any central data base.

1. [b]Group name[/b] — optional text field ("Club Monza", "Family").
   
   
2. [b]Group size[/b] — number from 2 to 12.
   
   
3. [b]Per-person entry[/b] — each person gets 2–4 letter initials, then the same inventory picker as the single-user flow; you finish one person, tap "Next person", and a running pooled total is shown throughout. The picker only opens once initials are entered.
   
   
4. [b]Build request[/b] — sends group_name and group_members: [{initials, inventory}, …] with the pooled inventory to complete the circuit like before.
   
   
5. [b]Result page[/b] — shows the group name, each member's initials and piece count, the pooled total, and the missing list is labelled "Still needed — missing from the pooled boxes".
   

The pre-existing two options "I have parts" and "Start from scratch" are unchanged, and the selected track chip stays visible on the group step.

Happy building!
