I checked - no one earlier than me. Perhaps that was a MM/DD vs. DD/MM thing (i.e. European vs. American date format)?
Well, I realized that that page exposes everyone's email address and could be easily screen-scraped by a spam bot (and probably already has been).
I notice I'm getting a lot more spam lately (

) and this could be one contributor (as the spam bot registrations increased they could have been scraping that page).
I'm going to put a Mod of some kind up to hide the email addy's and then repost it.
It's *very* lame that they don't have some kind of security on this already since I turned off showing usergroups it shouldn't show that page... Grrrr...
