I saw that QAvenDreamer added the mods tag to this question.
My question is why? According to my knowledge the mods tag is unnecessary, because Dota already has its own tag.
Just because the answer might involve a mod, the question should not use mod unless it is actually about a mod (which this question is not).
I tagged that question in February of '11. That's about a year and a half ago.
Site policy changes, and our tagging policy has been particularly turbulent as of late. It may have been a valid tag at the time, but waiting more than a full year is plenty of time to reflect before revisiting the deccision, so I think that, no, the mod tag is no longer valid on that question.
