I want to create a forum where I will have attachments available for download to registered users. I'd like to be able to see which registered users have downloaded which files. Is there a way to do that using SMF or PHPBB? I don't need to have 100% accuracy, as I imagine there are probably sneaky ways of masking your download, but this will be on a forum that is not really attracting people that would be using those methods-IE these are totally legit files that people will be downloading in a business setting.
PS: The files will live on my server, so I suppose it's possible to add a second layer where a user has to enter a password, but I prefer to just have the files as attachments on the forum.
Thanks for any help!
