while searching to find out what Enable IP Cache Timeout does, I found this thread.
What do you mean by tracking? do we just place say 168 if we wanted to be sure within 1 weeks time the same person didn't vote twice within a photopost category?
Assuming the admin does not see the ip or userid ?
I thought once a vote was cast, the user no longer could place another vote anywhere within that category from the testing I did so far.
