I know that you are working on the 2-way-sync with the myheritage.com website and the FTB software and I'm really looking forward to seeing how that will work.
Thinking more about the way I want to manage my tree it strikes me that the functionality that I'm really looking for is the possibility for visitors to give me feedback about misssing or wrong data on the family tree more than having them edit the data I would like to have an e-mail with the suggestion and/or an interface to merge the suggested changes into my family tree.
Features like "Report a mistake" and "Submit additional info" would be very welcome indeed.
It is rather embarrassing when people pass away without you being notified about that and then getting their birthdays announced.
Furthermore a simple link "Contact site manager" is hard to find. On sites you're not a member of, it's in the top left menu of the homepage. But on the site you belong to, you must find the profile of the manager first. (or am I missing something?)
