Everyone sees what is coming to the table - and whether it works at the table size.
Members pledge what they are bringing, and the event page groups it by who is carrying the box. Every game is measured against the live headcount - the members who said yes, plus their guests - so a two-player duel next to seven confirmed people is flagged before anyone packs a bag.
Every title the group plays, with its box art, player range, playtime and weight. Mechanics and categories are tags, so a member hunting for a co-op that works with four filters straight to it instead of scrolling.
Members record the copies they own - which language the box is in, what condition it is in, whether they can teach the rules, and whether they are willing to carry it across town. Two switches decide who sees a copy and who may ask for it.
Want a specific game on the night? Ask someone who owns it and is happy to bring it. The request lands in their notifications, one click turns it into a pledge, and nobody can be asked twice for the same title.
A thread under every game, so the rules argument stays with the game
Mechanics and categories as filters - deck-building, co-op, party
For clubs that circulate copies: a ledger of who has which box
