tags, or hightlight the text and press the # button beside the e-mail and "wrap" buttons.
2) First, take the screenshot using the "prntscreen" button on your keyboard. Paste it into a program like Photoshop and then save it. Goto:
www.imageshack.us or www.photobucket.com and cope the direct link or the link in [IMG] tags. I prefer Imageshack because you don't have to sign up, and it has a VERY convienant toolbar.
Hope this helps! :)
