What's an avatar?
Have you noticed that some people on the forum have a picture next to their posts and by default, you only have a grey silhouette image?
This picture is your avatar - if it's the grey image, you don't have one.
Avatars are a way of standing out from other users and make it easier for people reading forum threads to distinguish between posters.
The only rule concerning avatars is that they have not to be offensive to other community users. If in doubt, ask first.
How do I add an avatar?
Once you are logged in, click on the "Edit Profile" link on the main (light blue) navigation bar. Click on the 'Avatar' ta.
Make sure you have avatars enabled by clicking the "yes" radio button.
To upload a picture/image from your computer, click on browse, navigate to your desired image and click "open.
Important - click "update" - this should add the avatar to your profile.
If you want to link to an image that is on another website, type in (or copy and paste) the URL of the image into the Avatar URL field and select save.
