We've been using #Opportunity and #Issue to tag aspects of processes that we need to revisit to improve later but since the recent change to the tagging functionality, we're going to have to abandon these and amend all tags created to date, because it is tagging even without the hashtag.
So, what is everyone else using to tag their processes that doesn't suffer from this issue?
Presumably, you're using a word that isn't used in any processes?
