Look at the box just below the "Message" box where you write your post. There is a box labeled "Attachments". Just below that box is an instruction that says, "Click here to choose your file". It will lead you to a dialog box where you can browse to the file you want to use. Don't worry if it asks for a URL, just browse to the folder where the file is located and click on the file name. It will take a short bit of time but then you should see the location appear in the "Attachments" box. If you want to include another file at the same time, just click on the instruction again and repeat the procedure. It will add the second file behind the first. If you want to include a link to a website, that's were you can use the URL address to your website instead of a directory location. I hope that helps.
Thanks Thanks Bossman! I couldn't figure the darn thing out.. Finally got it to work.. Once again Thanks!
