To change the font on the posts and threads...I went to the top of this page....above the Quilting Board Headline....there's the sentence, "Welcome leiladylei54 Notifications My Profile Settings Log out " I clicked on My Profile. The when the page came up with my profile....located above the basic info on myself, there's a box on the far right as "Customize My Profile". A page should come up that has General & Buttons with a bunch of small square boxes with indicators of colors, etc. I just clicked on fonts, size, different colors for the different things. When you're done, then make sure you click on Save (at the top of the General & Button), then Exit. I think it should change your font size that you requested, different colors wanted for the post boxes, etc. Going to have to experiment regarding the different colors for the threads, posts (I don't know which is which). At least I was able to make my font and size comfortable for my eyes without having to always have my reading glasses on. Hope this helps.
