Why don't you upgrade to the latest version?
I've only just come across this program and on visiting the official website the very top message refers to v1.6a as the "Last Version" followed by a mention of v2.x beta. I assumed from this that 1.6a was the latest "stable" version and 2.x was in development.
Anyway - I decided to take a look at 2.0b34 and you're right it's a LOT different and much better.
I'm still not sure how to give the visitor an upload option - I do have upload enabled but I don't see how a visitor get to the upload page (if there is one).
Thanks
