What features would it need exactly?
Are after something that constructs the gallery pages with recips inserted and submits them accordingly, or just a service that allows you to enter the URL of a clean gallery and submit to a number of TGPs?
I was thinking of putting something like this together that runs on the server-side, so I'm curious about what features would be important.
Running something like this from the server-side would be many times faster, and not tie up the users PC.
