Our organization wanted to replace our dozens of paper forms with fillable PDFs and make them available on our corporate intranet. Unfortunately, as we added forms to the menu of our WordPress site the menu crashed. It seem that there is a maximum number of menu items that WordPress supports.
I searched for a solution and found BSK PDF Pro. BSK PDF Pro is easy to use for both the administrator and our users. It allowed us to categorize our forms into more than 15 categories. Our administrator uploads the PDFs to BSK PDF Pro and assigns them to a category. We have the BSK PDF Pro widget in a sidebar on our front page. The user can select a form category and then select the form by its name. The form then pops up for the user. Our users love it.
The folks at Banner Sky, who developed BSK PDF Pro also provide the support. Support is by email and response has been quick with clear answers. They have also been receptive to product improvement suggestions.
If you are looking for a solution to accessing PDFs from a WordPress site, I can highly recommend BSK PDF Pro.
