Okay, you totally miss understood me (if I wasn't enough clear, then sorry.) !
I was about to ask to handle differently the chat message and instend of displaying them with the default chat, use HUD, wich are more maniabe (you can set the position, colors, etc...) AND you can remove them (well, set a lifetime = store message in array, remove the one you don't want, refresh the chat every X seconds.).

I don't know why we're talk about HUD...

Anyways you can't remove messages because the chat messages are handled client sided, i'm saying you can just spam them with PrintToChatAll(), it won't remove the messages but it will hide them. Most people don't even scroll up the chat box anyways.

For the O.P.

public OnPluginStart() {
	RegConsoleCmd("sm_clearchat", ClearChat);
}

public Action:ClearChat(client, args) {
	for(new i = 0; i < 10; i++)
		PrintToChatAll(" ");
}

Damn... I'm gonna leave a plugin here to let you see what I tought.

Spamming the chat is a bloody fucking stupid idea and a waste of the server's time and the incoming client's time. Why would you think spamming a client with data (even if it is merely empty strings) would be a borderline good idea?

What purpose does this feature accomplish anyway? This is just a performance and resource sink for almost nothing. (My 2 cents over this idea.)

EDIT: If you want to really clear the chat you would need to spam enough strings such that even scrolling up the chat shows nothing.
