Mossen never touches money. The host buys the item with their own card, brings it home, and at pickup each neighbor pays the host their portion via Venmo, Cash App, Zelle — whatever the two of them prefer. The host's preferred handle goes in chat.

In-app payments would mean escrow, KYC checks, and money-transmitter laws state by state. We're a simple operation aiming to connect neighbors, so that's out of scope for now.

They can't mark the share as complete without buying it, and you can rate them poorly afterward, which shows up on their public profile. The friction of looking unreliable to the neighborhood is the enforcement mechanism. If a host repeatedly flakes, report them and we'll review.

The host can rate them poorly afterward — the rating shows up on their public profile so other hosts know what to expect. If a neighbor keeps no-showing across shares, report them and we'll review.

Yes, any time before pickup — open the share and tap Leave share. Your spot frees up immediately for the next person. Doing it last-minute when the host has already bought the item is rude, though, so try to give as much notice as you can.

It can't — once a single neighbor joins, the host can edit other share details (title, pickup, deadline) but the total cost is locked. If the host realizes their listed price was wrong, they have to cancel the share and post a new one.

After a share is marked complete, every participant can rate every other participant 1-5 stars with an optional comment. Average rating + count + recent comments are public on each profile. There's no anonymity — your name shows next to your rating.

Anyone signed into Mossen. Your display name, avatar, neighborhood, bio, hosted/joined counts, and ratings are all public to fellow members. Your email and any other personal details you didn't put in your profile are not.

No. We use your email only for sending you the sign-in code when you sign in and the notification emails Mossen sends you. Other neighbors only see what you put on your profile.

On any share detail or any profile that isn't yours, there's a Report this share or Report this userbutton toward the bottom. Tell us what happened in a sentence; we'll review.

Yes — open your share and tap Edit share. You can edit title, details, pickup, deadline, and spots while the share is still open. Price locks once someone else joins, and once you've marked the share as purchased, the share becomes read-only.

Warehouse bulk is Costco / Sam's-style household items — paper goods, food packs, that kind of thing. Home & garden bulk is topsoil, mulch, lumber, lawn seed. We may add more categories later, but those two cover most of what people actually want to split.

Not yet. Mossen launched in Portland and we're focused on building density here before opening to other metros. When we do, we'll let people in those areas know.
