I had a idea how to stop the /tell- they should give us a option that we can click on/off

On option, Free Company, Linkshell and people on friends list can send /tells.

Off option, it would be as it was before where you can get tells from anyone.

Either that bring over the filter from final fantasy 11 also there is already a option to shut off tells in general but that can be a problem when you cant see people you know send a tell which is why the On option would be nice.
