Over the years, I have only used one avatar for soltakss for all my profiles on various sites.
However, once I started publishing Jonstown Compendium titles, I have changed my profile picture to be one of the faces from the illustrations in the supplement.
I am so glad that I could change it from the Spiderling picture from Holiday Dorastor: Spider Woods, as that picture always creeps me out when I look at it.
My current picture is the Book Wyrm from Secrets of HeroQuesting.
Well, I suppose it must be a Greater Book Wyrm, as Austin Conrad has published a lesser version in his Monster of the Month series.
I am not sure how long the Book Wyrm will stay for, as I will probably change it when Holiday Dorastor: Seven Hills comes out.
