I hit the point where everything works last night. The main author Gavin Crooks was kind enough to meet up in the evening after a busy day to help me double check WebLogo's functionality. I fixed some errors regarding the logo creation buttons and problems with examples pages. We tested WebLogo by creating sequence logos from URLs on an ipad, and it worked. And it looks great! The images can be saved locally as part of the mobile device's image gallery. Working the controller logic that takes in the URL was a little tricky b/c we had to negotiate how Weblogo processes local files and data pasted into the textbox and needed to prevent a user from using more than 1 of the input types, as well as throw an error.
