Several tags were created in the past few days and have no questions: https://or.stackexchange.com/tags?tab=new
I suspect these were created in error. For example, see optimi.
Also, do we really need the lambert-w and wright-omega tags?
We can just remove the tags from the questions: whether those that have been created by mistake (like
optimi) or tags that don't add much value (like
time tag). Based on this meta post, tags with no questions will be deleted automatically.
