The synonym page currently says "Users with a total answer score of 5 or more, can vote for tag synonyms." I have +10 in the websphere-mq tag and cannot vote. Tried in IE and Firefox with scripting enabled. No vote, no error, just a dead button. Is there a bug? Is the explanatory text wrong?
You need 5 score (which is upvotes - down votes) (+50 points) on the tag to vote for synonyms, but you currently have 3 so far now.
