This extension is great. Especially if you need a simple contact form within an article. The site I installed it on has SEF turned on, and I had no problems at all. Very Happy. Thank you. Just a FYI, If you download the form and you're not sure what size to use for the fields. You can go to their website and use firebug to check out their specific lengths and heights on their demo. For the Textarea set the Rows to 4 and the Texarea Cols to 60 to get it to look like the demo text message area. Just a FYI.
