Well I imagine the whole thing would work in much the same way that ticking 'admin post' does when you're posting a comment; if you tick 'admin post' when writing the entry, the specialized styling is used, if you leave it unchecked then the entry appears as normal.

Suppressing the styling would be optional in the cases of admins who wanted their entries to appear the same as regular members (such as if they are posting stories as a response to a contest, for example).
