	RE: complete IE form That's some scary markup -- I can't even figure out what it was supposed to look like. Try pasting it with "pre" tags around it in this forum.

	RE: How to Obtain current web page url, and Grab a string from Url. I think your best bet is WatiN, http://sev17.com/tag/watin/ http://huddledmasses.org/tag/watin/ or the System.Windows.Automation classes (if all you need to do is get stuff from the URL).

	RE: Why is this appearing in my Add XML Element?
