When looking at the this question, I wanted to see what topics had recently been decided were on or off topic. I noticed that there were two tags off-topic and on-topic and they were used rather inconsistently.
For example a question would be "Is this on topic" and be tagged with off-topic or vice versa. There were even questions with both tags used.
As neither of the tags had usage guidance, I simplified both down to a single tag off-or-on-topic and added usage guidance
Questions about whether particular topics are off or on topic.
However there is also the scope
Use this tag when examining what is on-topic or off-topic, and why.
and there is the topics which has no usage guidance but is used in much the same way.
Can we make off-or-on-topic and topics a synonym of scope?
