Regarding your nice Sankirtana collections, this should be kept in a separate account so that it may help in some great emergency. You should become a little spendthrift. I know that you do this, but still I am reminding you: Revision history
Diff selection: Mark the radio buttons of the revisions to compare and hit enter or the button at the bottom.
Legend: (cur) = difference with latest revision, (prev) = difference with preceding revision, m = minor edit.
