Just a warning that the automatic pop-down menus at the top of the page can prevent the use of many of the important buttons and links which rest below it.

In particular, on my Firefox / Iceweasel browser, while using sufficiently large display fonts, the Copyright & Advocacy automatic pop-down can prevent my access to the Log In / Register buttons on the main PPA.com page, and the rest of the pop-downs prevent access to the navigation breadcrumb links Our PPA > Welcome > Forum FAQ, etc.

These problems only occur when the font size is large enough that the automatic pop-down menus are sensed while the mouse cursor is hovering over the links which are a few lines below. If I change the font size to a much smaller size, then it is finally possible to access the Log In / Register button and the various navigation links at the top of the page.

So, the PPA.com website and forums may be preventing some people from participating.
