When it comes to the themed weeks and the discussions for each, the new one is switched with the old, so to not clog up so many stickies. With the news sticky, i could probably get rid of it is chaos says so, i'd consider keeping the rules there, but again i can take that down if necessary as well.
EDIT: Much like Ryo said as well, hah. Erm but yeah, 3 stickies isn't a ton, its hardly any, so i don't see what to complain about in that respect. Its not like we're other forums with maybe half a page to a full page worth of em.
