I make a point of leaving a little thank you comment for each and every sheet I download. I feel it is the least I can do when taking something poeple have invested so much time and effort in. I go thru all the recent contributions pretty much every day (I download on average about 4-5) and I think that leaving a comment to each one adds maybe 3 minutes to the routine.. That certainly is worth it! I for one really like it when I open op ESL and there is a nice comment on one of my sheets. It makes you feel appreciated and don �t we all like (and deserve!) that?
