hello,
please see www.forallthetime.com
i coded this site years ago before i used validation
yes, i know its ugly 
a bit embarrassing too!
what happens if i leave all that be? not fully validated
i am tempted to simply leave it be
for all this time all the pages have worked fine (1 minor hic-up, no big deal…
very minimal)
never had issues (besides above)
is leaving the un-validated code ok, is it safe?
again, the page has been working all this time as is (beides above)
many thanks!
