Pming admins feels slightly awkward. Having to search them up first and knowing what their username is. There should be an option in the menu which will show the current list of admin and what their role is as an admin.

Eg.

Manager
Snk

Guns Admin
Meph

PR
Weird
Wazzah

and so forth.

Tap on the admin rank to show a description on what they do so that you don't pm the wrong admin. Tap on the admin's name and it will then show their profile. There you can pm them for any questions or problems.
