I somefimes shee critters saying things like "which private page made this tag!!!!!" buf I'd like to remind teh people's of teh worl thaf if you share a post wiff a tag that wasn'f originally in it, it won't show in general tag search, only in teh sharer's page tag search.
Also if u tag a post andf save it as a draft the tags will still show up in teh tag auto-complete as wew (see test post please ignore (2), which I just made up in a draft to test this hypothesisisis)
Andf knowing is half teh battel.
