There is a well established way to send a message to the MT which ensures that they see it. A post on the reflector is unreliable, it may or may not be seen by the MT.
I have activated every summit in G (England). Except that I haven’t. There’s five references that were deleted before I ever got to them due to them being found not to qualify.
It would be nice if they could be revalidated for a short period so I could visit them … but it would not be right.
Concessions have already been made with regard to the DL P100 summits. These are:
They have remained valid for many years since the formalisation of the objective summit criteria rule.
A long notice period was given to allow more activations before deletion.
Extending that notice period by one year would not be reasonable as then every association with non-compliant summits would expect the same.
BTW I have 3 P100 summits very close to my home QTH. They have never been valid for SOTA but I still enjoy walking on them. Sometimes I even take my radio! You can do the same in DL, and still log the activations in the GMA scheme.
