I found Cacheopedia (powered the same way as Wikipedia). It’s pretty cool and provides some guides on the site such as geocaching on a budget, how to get good coordinates and a GSAK tutorial.
I think the GSAK tutorial could be useful since that software isn’t exactly the most user-friendly and it’s certainly not the easiest software to learn. I remember many days I was frustrated and gave up on it. Now that I have the basics I do well enough with the software that I use it regularly, but I still couldn’t explain all of the features.
Anyway, Cacheopedia has some cool stuff so check it out. It looks like it’s good for new cachers as well as the seasoned ones which is always a benefit
