This website is no longer technically supported. Think of it as a ship that has lost its engine. The ship has not sunk yet but the crew has left and most of the passengers have also climbed into the lifeboats.
Eventually, the plumbing is going to stop working, then the lights will go out. At some point the ship will hit a large object and sink, taking the few remaining passengers down with it.
I migrated my oobgolf scores to SkyGolf360 17 months ago. It was simple and quick. I did not pay any fee to SkyGolf360 and do not pay one now. What the future holds is unknown. What I have received from SkyGolf360 for the past 17 months is a free, very basic membership. It is not as good as oobgolf was when things were running here.
I do not work for oobgolf. I do not work for SkyGolf360. I doubt very much that anyone else will respond to your questions.
