Hey Jaime,
Sorry for my late response. I've missed your thread.
About the first thing - this is really strange. Normally all moderators in the group should get the e-mail. Are you sure that the e-mail of the second administrator is written right?(I know it is stupid, but it happened to me once
)
About the second thing - when an admin gets the e-mail about the new comment he will be pointed to the page where the comment is, but he will be not to publish it through the frontend. Due to the design of the extension this is not possible right now, but it will be with a future version.
