I might sign up for the Pro account so that I can put in more data and, in particular, link to trees maintained by others.
But I'm not quite enough of an enthusiast that I can commit to doing so indefinitely - the rates are rather high for this kind of service.
If I leave in future, do any of the links get lost? I'm happy for my efforts to benefit others after my departure, but I won't sign up if the data will vanish when I stop paying.
