Support/Comments for MemberCheck

You can place snippets inside chunks but you need to make sure you alternate the type of snippet call, cached inside uncached and vice versa.

So if you are calling MemberCheck uncached [!MemberCheck!], you need to call your other snippets cached [[WebLogin]] / [[WebSignup]].

Is this for Web Users only?
or can it be used with Manager Users?

Is the manager administrator automatically ok for the chunks or
it needs to be put in a group?
