Admin Access for specific page(s)

I know this question is kind of off-topic but I need to come in and say firstly don’t add anybody… anybody….

ANYBODY!!

as admin on the site… At that level they can do everything you can do, or probably a lot more if they actually know what they’re doing :-p It’s a good way of getting your site hacked, compromising data and filling a few thousand more inboxes with junk.

What you’ll want is to add them as an editor, which doesn’t have nearly the same level of permissions as admin.

Secondly welcome to WPSE – please do give this a read.

Whilst asking for recommendations for plug-in’s is off topic it sounds like that’s probably the level you were wanting help at you may want to give this page a read. It recommends Capability Manager – sounds like what you’re after
