Disclaimer: This page and article were written by the developer, who is in dire need of formatting improvement for the article associated with this talk page because they are not experienced in Wikimedia and have no Wiki experience of any kind. The troll user known as STgiga on Wikipedia is unrelated to myself as I do not have a Wikipedia account at this moment, and that particular troll user was doing weird stuff before I had some degree of any meaningful internet presence, and my email was not the one that said Wikipedia troll used because I didn't know about that malicious user at all until I googled myself and got the nasty shock of finding that Wikipedia troll. Also, I never spell my name STgiga. I only spell it as stgiga, or St. GIGA, but NEVER with a capital T. If other parties refer to me with neither of those two handles, that is what they refer to me as, and they alone are the ones who do refer to me as such.
subcat/subcat2/subcat3 is supposed to be a hierarchy, is it not? Not just a list of categories. A Compression >> Encryption >> Transfer Encodings category hierarchy doesn't make sense to me. Encryption is not a kind of Compression. With multipurpose formats, sometimes we have to pick a category arbitrarily. I suggest that Transfer Encodings is the best option. -Jsummers (talk) 12:53, 30 January 2020 (UTC)
