I am seeing nothing like that myself. As I mentioned earlier, for me the font is quite large by default. I actually zoom our site out down to 80%. Here is what it looks like at 100% though:
Notice how the font is a completely different weight and size. Are you using something that changes the appearance of sites? It should be, I think, closer to what you see when you are composing. It would help to know what browser you use.
Here’s a Stylish theme if you want to use it:
@-moz-document domain("literatureandlatte.blinkio.co.uk"), domain("literatureandlatte.com") {
html {font-family:Helvetica, Arial, sans-serif !important;}
textarea { font-family:Helvetica, Arial, sans-serif !important;}
.common-questions__listing h3{font-family:Helvetica, Arial, sans-serif !important;}
.subnav li a:after{font-family:Helvetica, Arial, sans-serif !important}
.subnav li.subnav__buy-now a{font-family:Helvetica, Arial, sans-serif !important}
.subnav li a:active,.device-desktop .subnav li a:hover{font-family:Helvetica, Arial, sans-serif !important}
.subnav li.subnav__download a:active,.device-desktop .subnav li.subnav__download a:hover{font-family:Helvetica, Arial, sans-serif !important}
.subnav li.subnav__buy-now a:active,.device-desktop .subnav li.subnav__buy-now a:hover{font-family:Helvetica, Arial, sans-serif !important}
.subnav li a{font-family:Helvetica, Arial, sans-serif !important}
.common-questions__listing__section--open h3{font-family:Helvetica, Arial, sans-serif !important}
.features__icons h3{font-family:Helvetica, Arial, sans-serif !important}
.forum #viewprofile .details dt,.forum #viewprofile .profile-details dt{font-family:Helvetica, Arial, sans-serif !important}
.accordion__title {font-family:Helvetica, Arial, sans-serif !important;}
.text-filter {font-family:Helvetica, Arial, sans-serif !important;}
strong { font-weight: bold !important; }
.forum .forumtitle, .forum .topictitle, .forum li.header2 dt, .forum li.header2 dd { font-family:Helvetica, Arial, sans-serif !important; font-weight: bold; font-size: 1.1em; }
}
Yeah I have it on the list for them to look at. There are a billion links in the default skin and so naturally people are going to find the ones they prefer and forget the others. I’ve never even be cognisant of that link since I hit Home when I’m done with a thread. That works no matter how far into the thread you get. 
Hmm, I thought we had them put those back in—I even see the very top level has a place for that under the search bar. So yeah that should be in.
By the way I’ve merged this thread with the other one. It doesn’t really make sense to be discussing forum feedback in two different threads—sorry for the confusion though as that process interleaves the conversation a bit!
