Today, I asked my first question on WebApps.SE: https://webapps.stackexchange.com/questions/76126/could-not-find-driver-error-when-registering-at-ghtorrnt-org-dblite. (I'm fairly active on other SE sites.) My question was about a web app that didn't have a tag created for it yet, and since I don't have 300 rep on the site, I wasn't able to create the appropriate tags. Looking over the list of tags already on the site, none of them looked like they would have been appropriate for my question.
What is the right course of action in this situation?
