It would be very nice if the subscription center could become a page that can also be directly linked to from the portal.

For my requirements, we need to have a way to give the logged in user on a portal the option to check or uncheck all newsletters (like the "monthly newsletter" or the "quarterly newsletter", or whatever) from the portal.

I can create a subscription center and put it into a menu item on the portal, but this page will not work as it doesn't know what contact to update. Finding a way to link to the subscription center for the current contact, would be ideal.

In this way, I would be able to give my portal user a link like "manage your subscriptions" on the portal.
