This mod performs a simple, but very important task for many players. Namely, it blocks the execution of commands by players in the game chat.

This is great for map creators so that players do not cheat in their walkthrough, or for assembling with friends so that there is no temptation to use commands.

The mod is client-side, of course.

FAQ

Q: Is there any way to use a command through a chat with the mod?
A: Yes, in fact there is and it is made specifically. Use veystreks instead of slash and the command will be executed.
