For some reason, when I try to add any of the discussion, bug, or status-bydesign tags to my questions here on meta, that tag is listed in the suggestions list twice. Then, once I choose one of them, my question is tagged twice (as can be seen by this very bug report).
Interestingly, this has allowed me to put up to 7 tags on this question (5 plus two duplicates)
P.S. - Perhaps this belongs on meta.meta.gamedev? :-P
