OK, the tagging option seems to be kaputt? I just went to the What Made You Smile Today thread, and ... well, let me try to replicate it now with my FreeCell thread.
In the My Tags box, above "tag topic", I type in: game, freecell, bored. They all get added. There is now no more "tag topic" button under "my tags", but there's an "edit tags" link. I click it, the box and "tag topic" button reappear, and I type in: cards, solitaire. I click the "tag topic" button, and the answer is "Tags removed". But the tags have been changed to: cards, freecell, bored -- meaning that they added "cards", but only by throwing out "game"!
I dont see any logic at work, is it broken?
