Just two comments on font size option suggestions (which at this point in time i don't happen to require):
1. On Windows OS there are also the "Accessibility Options" with the "Screen Magnifier". Probably anyone who requires this option for viewing ALREADY knows about it.
2. There's probably a difference in using a Browser's +/- font size vs BPL Forum programming. Using just the Browser's ability to adjust Font/Text Size, the Posts (and WebPage) can become too wide to fit in the width of the Browser's window, resulting, at some point as font size in increased, the appearance of a horizontal scroll bar necessitating not only vertical scrolling to view the entire Post/Thread, but also horizontal scrolling to read a complete line.
Hope this explanation is clear. If BPL wants to discuss this matter further, they may just PM me.
