The tag synonym approval queue is not part of the regular review queues. In fact, it's a bit hard to find. There are currently five synonym suggestions dating from 2017 (yeah, five years ago) waiting for approval.
Please take a moment to visit the above link and cast your vote for the synonyms.
My request is specifically on behalf of the discussion concerning the conversion of reality-check to internal-consistency and the subsequent assignment of reality-check as a synonym to science-based. You can read more about that at If we can't burn the "reality check" tag, can we rename it?.
This post will be deleted once the synonym queue has been cleared. Thank you!
EDIT: While I greatly appreciate dealing with the one synonym required to resolve the reality-check problem, can't we get the other four out of the way, too? Isn't there a badge or something for participating in the synonym queue?
