There's some ambiguity in the etymological inference: Is it '(bi-month)ly' (as in, 'occurs once in a period of time comprising two months') or 'bi-(monthly)' ('twice monthly'). 'Bi-(monthly)' seems more intuitive to me, but (at least in the US), it seems I'm in the minority. I certainly wouldn't have the temerity to 'correct' someone else's usage.
Though either way, I think there's enough confusion that you basically have to just guess from context clues what 'bi-[time period]ly' means. This is certainly the worst of both worlds.
