Hold to claim for mailbox for trades/giveaways
It just seems to make sense, as this would be a good middleground between all the "trade buff" posts here in improveloop, which mostly ask for adding new content, and the current, non-existing "speed trades"
i am not asking to buff the sender's side! this sounds like a bad idea for:
-oversending
-if it's all automated mailbox size no longer matters
-if the site has jitter or desync you might end up holding on another item (sending spooky pie instead of stone is not ideal)
