Other than iprintln and iprintlnbold, what are the other ways to give messages to players? Ideally I would like to say a message from console to all players, or somewhere in the text chat box as we already have lots of messages in the iprintln area.

Thanks.

Just type /say and your message in the console. Or use a rcon tool like Rcon4Cod2.

I don't think my first post was clear enough, I would like it to be an automated response when certain criteria are met, in this case when a player achieves 10 kills in a row, I'd like it to print a message to all players, something to the effect of "playername is on a ten kill streak." So is there a way to make the console spam a message when the criteria are met as iprintln only goes to the individual person, not to everyone.

Hmmmmm I am almost sure this is possible, on a map one time when you pressed F in a certian spot, it would say something, but it said it to everyone, so they had to change it to Only to that person...There is probably a way to reverse it...

Most major mods have a killing spree functionality.
That's what you're looking for.

AWE has one, eXtreme+/WW2X have one too.

By the way, they use iprintln or iprintlnbold to print text on the players screen...
