Hello Peter!
Good to hear from you after so many years and nice to see you still around. Seems kind of funny saying that as I rarely seem to get online nowadays myself...but...I did rebuild my computer recently and even got a couple flights in
Who knows...maybe I'll even be brave enough to get back on VATSIM shortly
Re your questions:
I will see what we can do but no promises. We overhauled the website a number of years ago and it is now programmed in a new language that I am not as familiar with hence it makes things a little more difficult to program. I can reach out and see if I can contact the original web developer to see what options there may be but I think they have since moved on.
I believe today there is a way to have inactive pilots simply not show up on the roster after a period of time. If they log a flight then they simply show up on the roster again. I'll need to double check on that...
Will see what I can do otherwise.
Cheers!
