Yes, it means Moderator. Evening Star is one of the most helpful ones. (I've met him in person, too.)
Concerning these "wall posts" we are now exchanging: if you click ON my underlined name Copperfox, you can get to MY profile and leave a message THERE. Otherwise, I won't KNOW that you said something to me unless I happen to look at YOUR profile, because the software here does not notify others of what is said on your profile.
By way of a shameless plug: if you go in the major section called Professor's Writing Club, and select a thread called "Sonnets Here, In-House," you will find that almost all the poems I wrote there are personality descriptions of forum members. It's a get-acquainted device. Who knows, you might be the next one to be sonnetized.
