Someone may have suggested this already, but if they did I couldn't find it. I think it would be nice if the number of comments on a map was listed on the DLDB list, so that you can see when people add comments to your maps without loading the page of each one and scrolling down. Alternatively or in addition, you could have the option to get email notification of comments on your maps. Obviously it would have to be a preference that you would set, because for those who don't want it, or get an excessive amount of comments, it would be a hassle. Don't know how hard this is or whatever, but just a suggestion.
If any one want's to notify you, They could just PM you, You can look at how many comments you have in the edit thing...
When I go to the edit thing it just lists veiws and downloads, not comments. You still have to click on each map and scroll down. I mean, its not a huge deal or anything, but it would just be nice to be able to go to the edit page for example and just go down the list to see if you have any new comments. Also, about the notification, it wouldn't be for when people want to notify you, it would be to notify you of any comments you've gotten for your own interest, especially if you're looking to get critques.
Extremely good suggestion. I will keep it in mind for the future.
