Chat Manager v4.8

1. Compile crx_chatmanager.sma and crx_chatmanager_toggle.sma.

Move the compiled plugins in your plugins directory.
Move chatmanager.inc and cromchat.inc in scripting/include.
Move ChatManager.ini in your configs directory.
Move ChatManager.txt in your data/lang directory.
Write crx_chatmanager.amxx in configs/plugins.ini.
(Optional) Write crx_chatmanager_toggle.amxx in configs/plugins.ini.

The main settings can be found in the [Main Settings] section in the file configs/ChatManager.ini

ALL_CHAT -- if set to 1, all players will see all chats independant of whether they are dead or alive, this won't let them view the other team's private chat however; setting it to 2 will let them view the team chats as well
ADMIN_LISTEN_FLAGS -- players with this flag (or these flags) will be able to see all chats at all time
BLOCK_FIRST_SYMBOLS -- messages starting with these symbols will be hidden in chat (you can use this to hide messages starting with "/")
DEAD_PREFIX -- the prefix for dead players (DEAD)
ALIVE_PREFIX -- the prefix for alive players (you can leave it blank)
TEAM_PREFIX_T -- (Terrorist) prefix
TEAM_PREFIX_CT -- (Counter-Terrorist) prefix
TEAM_PREFIX_SPEC -- (Spectator) prefix

CHAT_LOG_TEAM_FORMAT -- the format that will be used when logging messages from the say_team chat
SAY_SOUND -- here you set a sound that will be played when sending a message in the say chat
SAY_TEAM_SOUND -- here you set a sound that will be played when sending a message in the say_team chat
Adding prefixes, chat colors and custom names

These things can be added in the [Admin Prefixes], [Chat Colors] and [Name Customization] sections.
The names are pretty self-explainatory, so I don't think that additional instructions are needed.
You can find examples and a syntax in the .ini file.
A new prefix, color or name can be added on a new line in the respective section.
When adding something, you can choose if you want to add it on a certain flag, name, IP address, etc.
In the list down below you will find all types of data that can be used when adding an extra.
flag -- adds the extra if the player has all of the flags specified in the "info" argument
anyflag -- adds the extra if the player has at least one of the flags specified in the "info" argument
name -- adds the extra if the player's name is equal to the one specified in the "info" argument
ip -- adds the extra if the player's IP address is equal to the one specified in the "info" argument
steam -- adds the extra if the player's SteamID is equal to the one specified in the "info" argument
noprefix -- adds the extra if the player doesn't have a prefix
For example, if you write "flag" "mnop" "[VIP]", players with flags "mnop" will receive the prefix [VIP].
If a player meets the requirements for more than one prefix/color/name, he will get the one that's highest in the list.
Defining chat formats

Formats determine how the chat is going to look. You can set a different chat style for each player in the [User Formats] section, but first you need to define the formats in the [Format Definitions] section. You can use the following placeholders when defining formats:
$admin_prefix$ -- the admin prefix set in the [Admin Prefixes] section
$dead_prefix$ -- DEAD prefix (and the alive one, if set)
$team$ -- player's team
$name$ -- player's real name
$custom_name$ -- player's custom name set in the [Name Customization] section
$ip$ -- player's IP address
$steam$ -- player's SteamID
$userid$ -- player's userid
$chat_color$ -- player's chat color set in the [Chat Colors] section
$message$ -- the actual message
$time$ -- time/date
You can also use the following ones, but since they are disabled by default, you need to enable them in the .sma file. To enable a placeholder, you need to remove the // from the line that contains #define in the beginning of the file, and recompile the plugin after.
$health$ -- player's health
$armor$ -- player's armor
$frags$ -- player's frags
$deaths$ -- player's deaths
$city$ -- player's city
$country$ -- player's country
$country_code$ -- player's country code
$continent$ -- player's continent
$continent_code$ -- player's continent code
