Its pretty much what you want it to be. On the old forum it was known as a Road Case and folks made periodic posts, stating a line in the sand or objectives reached. Some just charted gear acquisition (my early days was like that, times changes).
Best thing to do is to pick some of the on going Logs and see how folks present them and see if anything or any style floats your boat. It will be a good way to see what folk are recording in there logs and make a decision to how to present your own. No rules, no guidelines and no judgment.
If you’ve an hour or two to spare, see mine below. You’ll see the style had changed over the years, especially when we set up here on the new Community and things started changing.
