In the latest Meta discussion that I can find, consensus was reached to use the following tagging structure for the various flavors of Terraria:
terraria <- terraria-pc ✓
terraria-console <- terraria-xbox, terraria-ps3
terraria-mobile <- terraria-ios, terraria-android
However, today, there are zero questions tagged terraria-console. We most certainly have had (and still do have) questions about the console-specific ports, and I'm positive that there have been plenty of questions that have used the console-specific tag in the past. On top of that, the wiki excerpt for the base terraria tag specifically denotes that tag is for the PC version only, due to the existence of the console- and mobile-specific tags.
This came up when I noticed that the original version of this question was tagged with the PC-specific tag, and when I went to reassign it to the console tag, it didn't even show up in the autocomplete list because it has zero questions tagged with it. Since I didn't want to re-use a tag that had been deprecated intentionally for one reason or another, I added an xbox-360 tag as a stopgap until I could figure out what was going on.
Did some bulk retagging operation happen that I missed? What happened to all of the existing questions tagged terraria-console? If something's changed, what's our current policy on tagging Terraria questions?
