Having an Avatar is a bit of trend in the online world. It is a graphic that represents you online. It could be your picture, or it could be something like a toilet bowl or superman icon, whatever you want. Mine, as you can see, is the ship on the left. <-----
On this bulletin board, I have uploaded a library of marine themed Avatars for you to choose from to include in your profile and when you make a post. You can select your own Avatar, near the bottom of the "User / Acount Settings". You can of course make your own and upload it, or import it from another web bulleting board as well.
