Also Stan, any further on a subscription maintenance screen so that subscribers can change or alter their details without having to unsubscribe and re-subscribe?
Yes, I've mentioned it to you before. I've often seen ways subscribers can manage their details, like changing e-mail address and such like. It would be extremely handy.
Yes, I already took note about that feature request. v7.8 includes a new version of MLM with a bug fix related to uploading lists and duplicate checking.
