again a idea from our com:

If you want to do ACS, you contact people in your ally(with circular messages) or buddy list. If you wanna do ACS outside your ally, but you want to sent your message to several people, then you must repeat it several times.

To resolve this problem, make a system like the rpg system but then for ingame.
With this option you can choose which players the (RPG)message goes to, so that you don't have to repeat it.

Hmmmm... don't like... an easy way to spammers to send messages to all the universe

Not to all universe, but only the one you are playing

Sure... that's what I say... you're proposing an easy way to spammers ingame. Bad idea... don't like it

It is not for spam (abuse leads to consequence) <-- maybe an idea to put in a penalty ?
