Is it appropriate to link to your items for sale?

Do not use our message board for personal fundraising, for-profit advertising, or selling products or services, except in the specially-designated "DU Marketplace" forum. We will occasionally make an exception in cases where the product or service contributes to the Democratic or progressive cause, provided that you ask an administrator for permission before you post.

Your username, signature line, and avatar image

All registered members must select a forum username which will appear with all of their posts. Members are expected to take care when selecting their usernames, which cannot be changed once they have been selected. Do not select a username that could be considered inappropriate or disruptive to the community.

Members are not permitted to have more than one account on Democratic Underground.
Members have the option of including a short signature line at the end of each post, and donors have the option of uploading a small avatar image which appears in the margin next to each post.

Your signature line and your avatar image must adhere to the community standards for this message board. Do not use your signature line or avatar image as a means to disrupt the message board. If either your signature line or avatar image is judged to be disruptive, you will be asked to remove it or change it. The administrators have the final authority to decide what is considered disruptive.

Your signature line may not exceed 400 characters. This 400-character limit includes all characters, including spaces and URLs for links and images. You may have no more than one image (.jpg or .gif format) in your signature line at any time. This image may not exceed 500 pixels wide, 200 pixels tall, or a file size of 20 kilobytes. If you do not know if your image is in compliance, right click on it and select "Properties." You may not use any HTML code in your signature line except the special message board code for: bold, italics, links, center, and line breaks. You are limited to a maximum of two line break
tags.

Your avatar image should be in either .jpg or .gif format, and should be no more than 3 kilobytes. We recommend that you crop your avatar to exactly 48 pixels wide and 48 pixels tall.
