/say spam /tell spam /shout spam emote spam how does it work?

When you open (in-game) Menu>Configuration>Log Settings, the box where you click show or hide, under Linkshell (8) there are those options.

Let's see... Filters enabled (Show) will show you the message, and Filters disabled (Hide) will not show them. So, when you put OFF to "Say", you'll not see any character that has been sent in the /say section. Same thing for the tells and any other message. You can have a tab that shows only one information for example, like Ifrit's TP moves.

Did this answer your question?

Right but instead of /say

there is
/say spam
/tell spam
/shout spam
emote spam

Has anyone tried /? /say spam?

I tried them by turning them on hide, but I don't know if it does anything, i even tried spamming
