Is this really worth stickying, though? It hasn't been updated for nearly three years, and several (if not most) of the guides are actually very poorly-organized and shallow. One "guide" is just a request for tips and tricks for P-Moon, another is an opinion piece on Chlorophyte bullets, another is a guide for defeating slimes consisting of no real content other than "don't use the shortsword", and most of the hoiktronics guides are already in the T-MEC social forum, where they are accessible to their intended audience.
I mean, the building guides and a handful of others are good, but most people can find those by opening up the Guides forum list and ordering by most viewed.
