hehehe ... erm there is a post somewhere that says the parameters (10-50?), but I can't remember where to find the post or what the limits are, so I tend to stay between 10-30. The rest is up to your judgement - a really good comment gets top whack, a feeble I'm-making-a-comment-because-I'm-trying-to-get-into-the-weekly-draw gets 10 - if they're lucky.
