Reposting on this topic to insist a bit on the importance of that issue.
There has been several complains for people who spam servers.
It'd be nice if people could solve at least that annoyance, since it's often accompanied by some others (camping, etc ...) who piss them off too.
Edit: adding a few chatbeep sounds
- a softer one (I don't like it so much, but it should be less agressive than current one)
- a silent one (in order to mute chat beeps)
