My recommenders are technophobes. Is it OK to print out the recommendation forms so they can be filled out by hand and mailed to PiLA?

No, the technology and volume of applications prevent that. All application materials are evaluated online by PiLA reviewers.

As a courtesy to those writing on your behalf, give your recommenders plenty of notice so that they too are able to meet the deadline. Make sure they understand that their recommendations must be submitted via the online process. PiLA cannot process printed materials, including recommendation forms and letters. No incomplete or late applications will be processed.
