A large site with a lot of bloggers uploading images and attachments can eat up storage space in a hurry. An Admin option to limit the number of entries a user can make before the need to delete old ones would be a welcome option.

Question: Do I need to download the source version to determine which file types are allowed? Is there documentation on the module? It would be a nice feature to allow admin to determine the file types allowed.

The problem is that a devious user could drain your resources dry. Without an admin watch option in the application, you would never know that they were doing it unless your were watching your server stats all day long.

I know in Will's active forum module you can run an admin watch on a user that is questionable. Maybe that would be a easier implementation.

I would think that other users, of the module, who run high traffic sites must have considered the same issue.
