I want to build a site that contains markers for information for all users, but also have the ability for each user to update daily their own position marker.
So the information markers, (in one category) need to stay permanently.
However I would like the user markers to be updated each day as they travel.
Additionally, if the user doesn't update for say 7 days, can the marker change colour?
And if the user doesn't update for say 21 days, can it be automatically deleted?
Thanks for any guidance.
