Just wanted to second Laura's question.
The issue she raised crossed my mind too -- sometimes a series forms a complete story in itself and so it seems appropriate to nominate it as such, given that there is no series cat this year. So, for example, if the total K count of the series bumps it up from short to mid-length or from mid-length to drama is it okay to nominate the series in the longer category even though each part of the series may be a short story? Yet somehow, it doesn't seem quite right to do so, given the structure required for say a mid-length story compared to a vignette - apples and oranges etc.
