Current version: 0.2.0~ynh1
Potential alternative to: ClassifiedAds.com, kleinanzeigen.de
A decentral federated small advertisement platform
flohmarkt provides its own http server that can be used stand-alone to show small ads that registered users may publish.
Registration works through the server itself and can be switched off (to run a server for e.g. only one person or only the persons that had been registered until that moment).
To register it's necessary to provide an email address to which a confirmation link is send.
Registered users can access a simple form to publish there small ads. The small ads can be looked at by anybody who is able to reach the website.
Federation
To communicate with someone who published a small ad the server hints to an unregistred user "To answer this offer please log in or create an account. OR use another fediverse-account".
The small add visited turns out to be a note in the fediverse. It's url can be opened with your favourite fediverse client at the server you're already registered to. You then can boost the small ad like any other note you read.
Or you can use your account to answer the author of the small ad if - and only if - you mark your note as 'private' aka 'direct'. This way you can contact the person.
It's also possible to follow accounts on flohmarkt servers like any other account in the fediverse to get new small ads published by that account in your timeline.
Federation between flohmarkts
At time of installation the software asks for the coordinates of the community it should be for and the radius it should be used in.
This is an offer to help make the goods that might be offered travel less far. A flohmarkt can manually federate with other flohmarkts in its range showing all their goods on its page.
This is not ment to be a restriction, but a nudging to build local communities. These would have the advantage that people could trust each other more, because trades face-to-face could be more common.
More information
Generally the wiki is a good source of information.
Important infos before installing
use of couchdb
flohmarkt expects to install CouchDB from the Apache repository for its use. Installation of flohmarkt might break already existing installs of CouchDB.
flohmarkt will probably not install if you're already running an instance of a couchdb

multiple flohmarkt on the same subdomain will not work
flohmarkt needs its own subdomain to be installed on. Some of the discussion about this can be found here:

No integration in yunohost user database
flohmarkt mainanins its own user database in CouchDB. Users have to register to flohmarkt to get an account. Registration cannot be restricted to yunohost users.

removing
When installing flohmarkt on a a domain and letting it talk to other ActivityPub instances it will propagate a key associated to your domain. If you remove your flohmarkt from that domain and loose that key other instances might not want to talk to you anymore after you installed flohmarkt again on the same domain generating a new key.
list of instances
We apreciate a lot if you run an instance of flohmarkt and will publish your instance on the wiki if you open an issue asking us to do so.
If you're looking for another instance to federate with the list on the wiki is a good starting point also.
