Apparently, Gersic.com hasn't been updated in awhile. Many of the most popular plugins are no longer hosted at the links. The discussion board was shut down by gersic in 2011.
www.kvraudio.com allows you to search for only free plugins, by category and it's kept up to date sort of on a 'wiki' basis.
I used to hop back and forth between gersic and kvr, but kvr had a more vibrant discussion community with developer support usually right there as well.
I remember getting one plugin from gersic that I couldn't find at kvr back in the day, however.
