Introduction

============

This module logs the conversation of chatrooms running on the server to

Prosody's archive storage. To access them you will need a client with

Usage

=====

First copy the module to the prosody plugins directory.

Then add "mam\_muc" to your modules\_enabled list:

``` {.lua}

```

mod\_mam\_muc needs an archive-capable storage module, see

[Prosodys storage documentation][doc:storage] for how to select one.

The store is called "muc\_log".

Logging needs to be enabled for each room in the room configuration

dialog.

``` {.lua}

muc_log_by_default = true; -- Enable logging by default (can be disabled in room config)

muc_log_all_rooms = false; -- set to true to force logging of all rooms

-- This is the largest number of messages that are allowed to be retrieved when joining a room.

max_history_messages = 20;

```
