As below, suggesting tag synonyms requires both 1250 rep and an answer score of 5 or more on questions so tagged. As below, my tag synonym suggestion failed today for the reasons described here.
Sigh. Hoping one of the moderators will create the tag synonym described below. Thanks.
Today I created the tag norway and set out to suggest the tag synonym, "kingdom-of-norway. The latter attempt returned an error because even though my question tagged norway had an upvote score of 10, I do not have an answer score of 5 or more on questions so tagged.
StackExchange requirements for suggesting tag synonyms seem too restrictive. A more reasonable permissions requirement would allow suggestions by a user with necessary rep who has a question or answer score of at least 5 (on the tag).
