Your profile is what other members see when they click on your username in the Blab forums. Your Profile displays a variety of information about you - when you last logged in, your Friends on Blab, your website address, the number of posts you have made, your collection interests. It also displays Visitor Messages, as described elsewhere in the FAQs.
Only paid members may customize colors and styles. You can edit your profile from your My Panel or from the Quick Links menu in the upper right hand region of most forum pages. You can change the information in any of the fields in your profile, except your username. To customize your profile, go to My Panel, and from the left navigation pane, select "Customize My Profile." The various fields will only accept hexcodes - alphanumberic combinations that constitute the HTML expression of colors. Click the dashed areas next to the blank fields, and you'll see a color chart: select a color and the appropriate hexcode will be inserted. For more colors, do an internet search for any of the number of color picker sites, such as this one. The "Background Image" field does not work.
