Markup & Pings
HTML should work in pretty much all areas of the site you can post on.
You can ping or mention a user by using @username. If they have not blocked you and are not in quiet mode, they will be notified of the ping. This only applies to threads, posts, comments and bulletins. Users will not be re-pinged if the post is edited.
You can ping a character by using @characterID, for example: @1 or @123. This will not notify the user, and simply formats the character link.
Adding a user to your authorization list allows them to view your protected characters and bulletins. You can also set custom image visibility options for authorized users; for example, allowing authorized users to view your un-watermarked images, whereas public users cannot.
Blocked users cannot contact you for any reason, including messaging you, commenting on your profile or any of your characters or bulletins, requesting links to any of your characters, pinging you, or authorizing or subscribing to you.
Forum posts from blocked users will be hidden, as well as your posts from them. Characters from blocked users will also not show up on the front page.
Blocked users will automatically be unsubscribed from your account. If they attempt to view your page or any of your characters they will be told that they are blocked, but note that this will not stop them from viewing Public characters by logging out.
Quiet mode blocks everyone on the site aside from users on your authorization list.
