G'day Nathan,
Fadix: Questioning an admin's capability is generally Not A Good Idea[tm]. I wouldn't resort to this myself and I've said some things that have been pretty disruptive.
I'm not sure what you mean by "questioning an admin's capability", but as a general rule, questioning admins is a Good Thing. We all need to have reasons for what we do, and we should be happy to give those reasons to anyone who asks.
(This is not to say I support those who hysterically scream wild accusations of "ADMIN ABUSE!!11112" every time an admin does his job properly, but rather that simply questioning an admin is in itself something we should never in a million years try to discourage. If an admin's wrong, he's wrong.)
