Happy to help! When I got into collecting several years ago, one of the ways I learned was to just read every post on this forum and to see what the more experienced users had to say. Obviously, there are exceptions, and there are some users here who are particularly extraordinary (Mike Diamond, Tanman, and TropicalBats, for example), but as a general rule of thumb, you can expect anyone with over a thousand posts to probably have some idea of what they're talking about (of course, many experts will also just happen to be new to this forum, but people with a lot of posts are kinda like a verified twitter account). You can also usually tell pretty quickly from reading a response if a person is an expert. Anyway, highly recommend just reading the responses each coin gets and seeing why or why not each one is deemed an error/variety. You'll pick up a ton of information very quickly. Beyond that, error_ref, variety vista, Wexler's die varieties, and coppercoins are all essential resources for anyone interested in this hobby.
