Can the default font size for typing a new topic be increased for those with diminishing eyesight? It looks like it's 10 or 11 px at the moment, 12 or 13 would be better the size of Heading 2 but without the bolding, perhaps?
In the meantime...images don't work.
PS The image above wasn't there when I originally wrote the post, since Julian's fixed the formatting, the image is now there.
