Features, help pages, and policies – on hold
Since a company I'm with has finally asked me to begin writing a chapter for a book on academic writing, I'm getting back to the Manual of Style for the practice. And now I'm actually writing the chapter, this is on hold again.

Roll of Years – Occasional
Since almost all the Category:Years pages were copied wholesale from The Grand History of the Realms and other sources, I've been steadily rewriting these since some time in 2012. At last, in December 2015, I've caught up and rewritten all the copied entries, as well as applied general copy-editing where necessary and added references to many. Now to continue checking and polishing the Years pages through the classic play era and into the post-Spellplague years. 2787 Years pages -2530 checked/rewritten Years pages - 69 checked/rewritten Years pages = 188 Years pages to go! ~93.255% done
 * Completed to 1369 DR
 * To do: 1370 DR onwards
