For those of you who are interested, I've written an online tool to dynamically generate VBScripts to change IE's proxy server. I wrote it to be used as a really user-friendly method of getting around my school's censoriship methods (which use a filtering proxy).
Check it out here:

Username: crazy
Password: hijinx
Once I get the RSS and TXT feed exporter done and sent to Insomniac (and he impliments it), the script will auto-update its proxy list every week from the newest list from the transparent proxy forum.
If you have any suggestions, feel free. I'm always looking for ways to improve it. As for the "Machina" author, that's just the pseudonym I used to hide my identity.
