Years since I'm using ElkArte and just now I realized I can send an email directly to a member by clicking mail icon. :D before I just assumed that is to pm the member.
now i want to know on how to disable it. i find some hints from smf but the location/options is not applicable.
thank!
IIRC it's not possible (yet) to disable it entirely.
You can remove the permission though: "Send emails".
