On the avatar front we have an issue because of the software we are using to create and manage this site so tomorrow I will be adding a form for you to send us your avatars so we can get them added. No plugin will work at this point – I just did research.
You can use Gravatar to set your avatar for the email address used for the site. I discovered I didn’t have a Gravatar for my business email in the process. 🙂
