Identifying community administrators in jquery.postform.js

[purplecat]

I've been adding a stickies module to the entry post and edit pages as part of my work on Bug 2152 (multiple stickies). I had this set up so that if the user posts to a community all the sticky options quietly vanished and a little message appeared saying you couldn't sticky entries in communities. Unfortunately, as fu pointed out, administrators can sticky entries in communities.

My problem is I have no idea how to identify a community administrator from jquery.postform.js (which is where I'm controlling this from). Is that possible? If not is there an obvious work around?

If the worst comes to the worst I can always have the message direct people to Organise->Manage Accounts->Display but that wouldn't be optimal.
