Sceadwian,
I do get a notification to my e-mail if someone posts a reply. Not everyone posts a reply, though, even if they are interested in the information. The attachments also have a counter that tells me someone is interested enough to download the data. That is why I usually zip up the associated files and look for the number of times they were downloaded. This has worked well for me in the past. All I am saying is that counter increments suddenly stopped and this may be due to the recent upgrade.
