I would like to +1 this request please, with the addition of an option for a guest to login using their email address if they don't use social networks.
I think having guests checking in/logging in would also be useful for traceability if it is found that someone has been abusing the guest network.
We use a separate AP for this at the moment called Guest Internet but it would be great to have it integrated on the Meraki Go APs instead.
