Thanks, Nate! Appreciate your attention to detail. As Lilly says, many of these tags are used in various ways not visible to the public. In private categories and personal messages with customers. I look forward to bringing some order to the /tags page!
I just tried adding phpbb to the topics currently tagged phbb and it did not work for some reason. That’s weird. phpbb is in the Migrations tag group but that tag group doesn’t limit who can use the tag.
