@ support: Yes, I just got impatient and wanted a fast answer..!
Nice to have all the info in the "Nebula tip of the month, #11, feb 2011". But I reckon it would be sufficient in most cases to get a "to the point" and short answer like TrancendingMusic just gave - no sarcasm intended or anything like that. Just a thought!
Suggestion: Could you please update the FAQ with this question and the short answer (and a link to the more extended explanation in # 11, Feb 2011-page). I reckon more people here would appreciate that
