Well, you could go into Settings -> General -> Accessibility -> Larger Text; adjustments can be made there if the app supports 'Dynamic Type' - if not, then no luck - NOW, I've not tried this feature so this is not a guarantee; also, you would have to go back & forth in Settings when wanting to return to normal type size.
Of course, you could always use a web browser, such as Safari, and read the forum's post from the regular website URL, in which pinch-spread finger maneuvers would work? Dave
Hi Johanna - nice find! And works - just gave it a try - I do most of my reading & posting in the forum on my Macbook Pro, so I've not really explore the features/settings of the iPad app, so good to know options exist. Dave
