Except that it is not version 4 of the hack. Hack Versions do not necessarily correspond to a specific software version it is made for. Especially when this is actually for UBBThreads and Photopost. Using that logic. I should jump it up to 6.3
Some people say version 1, 1.1 ,1.2 ,1.3, 1.5, 2.0 blah blah
I tried to make it simple. First version was for Photopost 3.2 which used Global calls.
Second version was when Photopost 3.3 came out and uses Stylesheets.
Third version was released when Photopost 4 came out. The hack has essentially remained the same throughout with a minor change here or there. The only change for this version was to add a global statement escluding two admin files so the new ADMIN FRAMESET would operate. Of course there is one main change this version. I took the time to make it simple on you and made a straight forward text file to use instead of the difference reports.
