I'm a puristic person and perfection maniac. Every of tens of thousands of MP3 files in my audiobook library must have a precisely filled up ID3 Tag and correct file name. For most operations on both tags and filenames, I'm using my own piece of software, written in Delphi years ago. However, since it does not support operations on ID3Tagv2, I was forced to strip these tags manually, using "magical" key combination in Winamp (see below). But, for large set of files some batch program must be used. And here you'll find short notice on some of them.
GitHub is the best place (known to me) for doing a not-too-much-demanding management or collaboration of not-too-big projects. It offers you (of course!) repository hosting, powered by simple, yet effective bug and issues management and wiki pages for help or guides for your project. And the only problem, that beginners usually face, is hosting images for that wikis. GitHub allows you to upload images to issues in issue tracker and does all the dirty work of hosting them for you. But, a bummer appears, when it comes to images in wikis, because
Add image button in any wiki page editor allows you to enter URL only and there is no way to simply upload them to your wiki.
