[QUOTE=Jayder;454101]I would find it useful if we had a shared spreadsheet of what was needed to be done.[/QUOTE]

All of the ones that Madpoo posted recently have been taken.

If you want a few suggestions in the same vein(s) as the recent ones, you might try:

Updated list
 

Here's a new list of strategic double checks.

It's a look at the monthly counts of bad/good, but if they don't have a monthly stat it'll look at their lifetime bad/good and go from that.
