I've made some pretty substantial changes to the alpha sheets behind the scenes, and to the Pathfinder [Legacy] sheet in particular. Please try clearing your browser cache, or post in the Experimental Features forum if there are any issues!
At this point, we highly recommend that all new Pathfinder sheets be created in the alpha and that existing Pathfinder sheets be copied into it via the 'Copy to Sheets Alpha' link in your regular sheet list
As for me, my bio will be added to the roster by tonight. I'm headed to the field from tomorrow morning until Friday (don't worry interruptions like these won't be too frequent) so the earliest I can actually get started will be the weekend.
