adaliabooks: When you get to that stage Barefoot could probably point you in the right direction (of how to post stuff, you'd need to be able to log into an account first, which the gogrepo or linux downloader devs could probably help with) as he presumably figured out all the right calls etc. when he did the quick post and quick reply boxes.
Well, well, well... that would be of great interest to me. :)
To be honest, even if I managed to get a really robust and reliable script to spot all the file and price updates, I'm not sure I would be able to post the diff logs on a regular basis. Being able to automatize the posting process would be a huge improvement!
I'll make sure to contact Barefoot and/or the gogrepo and lgogdownloader devs for help if I reach that stage, thanks! ;)
