# Introduction

This module lets users specify which of the group chats they are in are

less important. This influences when

[mod_csi_simple][doc:modules:mod_csi_simple] decides to send

stanzas vs waiting until there is more to send. Users in many large

public channels might benefit from this.

# Configuration

The module is configured via ad-hoc an command called *Configure group

chat priorities* that should appear in the menus of compatible clients.

The command presents a form that accepts a list of XMPP addresses.

Currently there is a single priority, *Lower priority*, which is

suitable for e.g. noisy public channels. mod_csi_simple considers

groupchat messages important by default on the assumptions that smaller

and more important private chats are more common among most users.

A message of type groupchat from an address in this list will not be

considered important enough to send it to an inactive client, unless it

is from the current user or mentions of their nickname. **Note** that

mention support require the separate module [mod_track_muc_joins]

to also be loaded.
