I cannot see the point of this person �s submissions as they are all blank or virtually useless. He only has 3 points, and I cannot understand why anyone would even download a worksheet that is blank - so in a way he/she is not taking any excess space as the contributions are blank!!!!
As people surf through the daily contributions, you should look at blank previews and see if they are really blank or there is a mistake with the preview. If it is blank, then check the box at the bottom and report it as blank or corrupted.
I feel absolutely sure that Victor does not have the time to check every single submission before it appears on our screens, but he does seem to make the time to react to our feedback through the reporting procedure.
So help him, and help others by reporting such worksheets directly, by checking the boxes and let our glorious webmaster deal appropriately with the miscreants.
