If you set the config for ulx logEcho to 1.. (so ulx logecho 1 in console or through your menu) it'll show anonymous for players who aren't admins on your server.
Instead of: Jakey slapped Bob with 10 damage.
it would read: (Someone) slapped Bob with 10 damage.
in this mode, the (Someone) would show the admin's name for other people with the permission to see it.
There is currently no way to make this ONLY echo to admins though.
