Hello, personally I am not interested in podcasts but thinking about offering it to my members. I have a question, will podcasts only work when linking directly to the mp3 file, or is it ok if they go through a php script? Because I have a script that keeps track of the clicks and want the podcast plays to count as clicks as well. Thanks

Noone knows?

I don't know the answer, but I can say that you can easily find out yourself
The easiest way to find out is to have the files up for podcasting - one is in mp3 format and the other will be read by PHP. If you get both, then you are good to go.
