Increase the font size in the forum posts.
I suspect that many people like myself use a tablet device to view/use the forum. In my case I use an iPad Mini and find that the text size (font size) is very small - for me at least it is a struggle to read.
Yes 'pinching' the screen helps in one way - but is counteracted by then having to scroll horizontally.
So my suggestion is please increase the font size in the forum posts.
