My younger brother (10) likes to play Garry's Mod, but when he plays online, he sees lots of bad words in the text chat. Is there a way he can play online, but with the text chat disabled? Or if that's not possible, can I set it up so that the profanity is filtered out?
hud_saytext_time 0 should do what you want. It's a client ConVar that controls the amount of time chat messages are visible for before decaying -- obviously setting it to
0 will cause them to not show up at all.
Do note that you can still see messages if you actually open up the chat: if that's an issue, you can simply unbind whatever keys you use for chat (
y by default).
