Still playing (ok hitting it with a stick) around with this.
Redo htaccess to include php.
Contact admin to set up db and crontab.
db crash, add another 4 solid days to re add all the lost ads (my fault).
Remove ALL SSI includes because you can't have SSI and PHP on the same pages.
If you have a lot of different ads on the same page, ie 3 different bbw sponsor ads (with text below) on the same page, it's a real resource hog.
With All the pop up free ISPs out there (that simply block javascript) I won't ever use that option to cross domains.
Would I recommend it? Yes, given you know the pitfalls.
What would be better? something written in C++ and FREE
Until then, this will have to make do.
