Just a thought as an addon to the FCRP town, disabling mainchat would be perfect.
You often get lost in the messages sent to you in localchat, due to spam on the mainchat. If there are some important messages to receive, as an ex. from administrators, they can just easily pm it over.
I can't tell you the amount of frustration there is when mainchat is being spammed with nonsense, whilst you're trying to have an actual convo in localchat.
