G2G Tags are used on your WikiTree profile for the purpose of following G2G posts that are related to the tag subject. They are not used on other profiles other than your personal profile,
I think what you may be referring to are categories. Categories are used to group profiles that have something in common, For more information on categories.their use and creation contact the Categorization Project
Profiles that are currently managed by Southern Pioneers can be found in the project watchlist and the following project category: Category:Southern_Pioneers
I hope this helps.
Using wikitree+ may also help. You can get a list of all the profiles you manage (not your entire watchlist). The last column will show categories and templates used in them.
Rhonda .. are you looking in the correct place? Categories show up at the BOTTOM of profiles now (and for some time). They will not show on preview, but once you have saved the profile, they DO show up as a teeny link to the right: [categories]
If you click that link on the profile/s, it will take you to where the categories are shown.
