Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna



Always scroll to the bottom of the page for the main download link.
We don't believe in fake/misleading download buttons and tricks. The link is always in the same place.
