Ned found a nifty little feature I thought I'd spotlight. With this new version of the software, you have the ability to set your display name. Normally your username, the name your login with, appears by all your posts. The display name will replace "billrob458" with "Bill" on all form posts, site lists, etc.
In the upper right corner click on your username; it will take you to your profile page. From the profile page, click on the site options tab. You will see a setting "Enable DisplayName". Switch the radio button from "yes" to "no". Then go to the "About" tab. On this tab you will see a Name text box. Enter the name you want to be your display name. Click save and you're done.
