There's a field in your member profile called website/blog; adding your blog address will create a link out of your Dixie Pieces user name. From the Forum then, anyone can click on your name and go directly to your blog.
If you didn't add your blog address to the member profile when you joined and would like to add it now:
Go to the Forum or Gallery
Click on the Profile link under the "Welcome, [yourname]!"
Click on Edit Profile
Add your blog address to the Website/Blog field
Click on Update Profile at the bottom
