Some time ago, I got into the code and manually made the system link to the author page like you see here: http://www.drkatiegriffin.com/blog/ but now that I want to take that away since we have guest bloggers I can't remember where it is.

Does anyone have any idea what file I might have put that code?

One way to find it would be to download the Atahualpa folder from yout host to your PC, then download a fresh copy of the theme to your PC and run a program that will compare the two folders for differences. On the MAC there is a great program 'TextWrangler' that will do this. Being a mac person, I have no suggestion of a program for the PC

Thanks Juggledad! I have Text Wrangler. Didn't know it did that too!

under the search tab'Find Differences' you can select 'folders'
