I love this subreddit. Due to certain limitations, however, PDFs are not pleasant surprises during the day for me. It is common reddit courtesy (though certainly not a reddiquette requirement) to include a PDF tag with all submitted PDF links.

I know that the entire point of this subreddit is PDFs, but on the front page, the subreddit ID is incredibly small, and does not serve as a very good indicator. I think it would be a good idea to simply preface your links with [PDF] so as to let people know that they will be clicking on a link to a PDF.

I am not sure, but is there a way to automagically append or prepend text to a link title? If not, there should be!

Thanks for considering the request!
