This question is a parallel to this question
Making a select-type custom profile field actually *required*
but it seemed correct to separate the two aspects in two different questions.
I am running a pair of sites using MSM and, although I have a separate registration form for each site (i.e. different template, different URL), there is no way of actually linking a newly registered user to the site they registered for - as all new users end up in the same "Pending" list, regardless of which form they filled in.
This is one of the strange features of MSM, where some membership features are site-specific and others are not.
Is there anyway of linking new registrations to the site they have registered for?
I know that I could have them placed automatically into a site-specific member group, but then you lose the ability to activate multiple users while sending an activation email - which you get when using the "Pending" list; something my client wants to keep.
I have tried creating a custom profile input field and placing in the registration form as a hidden input field with its value fixed, but if the field is not configured as visible on the registration form, the system won't write the content in the database; and, if it is visible amongst my custom profile fields and is included in the form as a hidden input field, then it is effectively appearing twice.
