I'm using the acronym package, and using the smaller option because that is a typographic convention.

\documentclass[a4paper]{article}
\usepackage[smaller]{acronym}
\acrodef{DLL}{Dynamically Linked Library}
\begin{document}
The plural of \ac{DLL} is \acp{DLL} but that `s' just looks way too tiny.
\end{document}


Compiled with pdflatex:


But the plural form of the acronym (\acp) appends an s but this is much to small in my opinion, and looks off.

Should I try to fix this or this typographically accepted? I was thinking about a new command \DLLs (and \DLL) which added a normal 's' but that just feels dirty.


Question: What might cause "junk after document element" error?
Answer: Solved. External feed idea was correct, figuring out feed was slightly more complex.

I had installed Core Control plugin and enabled log of HTTP requests.

Then it was just sitting and waiting until error re-occurs and checking which feed was downloaded at exactly same time.

Subject feed:


belonged to one of recently installed plugins;
was fried dead with PHP fatal error instead of content.


And feed validator was giving exact match on it:


  line 1, column 0: Undefined root element: br
  
  line 2, column 0: XML parsing error: :2:0: junk after document element


PS I am not sure which answer better to accept, this with exact solution or EAMann's with ideas and discussion? Edit: can't accept my own for two days anyway, that one it is.
