Ok,
I am interpreting the silence as consent and will do the changes I proposed.

I would like to propose refactoring that a little. I would propose to create SubscriptionRequest and -Response objects containing SubscriptionItems. This way the API would match the Read and Write parts. Above that it would allow subscribing and unsubscribing to multiple addresses in one request. It would also return a response object that can be used to unsubscribe again. The current solution, passing in the same combination of parameters to the unsubscription as used when subscribing, is a little fragile in my opinion. What do you think? Chris
