Thanks for promptly explaining this. I do agree, as stated in my previous comments I've never come across a job posting that requested more or less than two connects. I've submitted 69 proposals so far, and all of them (except invitations to interviews) required two connects. So I guess we have a rule here - 2 connects per submitted proposal, if it isn't an invitation from the client.
My question is this: Why are 1-5 connect options mentioned in the Help Center if these options aren't applicable? Maybe an edit to the content would be a good idea?
