For tagging, many use Foobar and you need to get the Live Show Tagger plugin (this is all free and not dangerous). There are others. If you tag the files, the info appears when you use a player, either software or hardware. Tagging is important to torrents because if you don't the people who download can't do the tagging themselves without messing up the folder for uploads and so won't be able to seed anymore. Plus you save many people a little bit of time, so please do! Live Show Tagger uses your text file to guess what you want in each field. It is very syntax dependent unfortunately, gets screwed up for some of my naming conventions and if there are non-standard characters or numbers that aren't track numbers in filenames.
When you do upload on Archive, be sure to choose Live Music Archive. When entering the folder name, after the last extension (dpa.flac16 for example, no leading period) hit tab instead of enter, then hit enter when it says the folder name is available.
