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.
