I have heard from some people that the text on the forum is too small to read. I have found a solution to this. Click on your name in the top-right-hand corner of the forum and it will take you to your Control Panel. Go To My Personal Settings, Then go to Advanced Settings.
Name > My Personal Settings > Advanced Settings
Here you can change a variety of options and there is one for "Font Size" Default is 13px.
Increase the size to which you desire, this should help older viewers read better.
Click "Update Settings' for the changes to take effect.
