It's a good idea (and I've also noticed the very outdated guides on that thread). Check the Main Page on the wiki - in the top two blocks, "basic training" and "clockworks handbook." There's a ton of links/guides in there - including links directly to category pages, which function in a similar way to Eury's thread. We don't want to be overly repetitive on the wiki (like making pages that already pretty much exist, but with slightly different titles). Anyway, check over those - if you feel anything is missing, inaccurate, and so on...then add to/edit existing pages, or make a new page if you absolutely can't find what your target subject happens to be. For example, a wiki page linking to forum threads has been discussed before, but never heavily considered as far as I know due to standardization issues and blah blah blah.
IMO, having guides that are outdated is very harmful to new players - we don't have the same "sharing and caring" dungeons we used to, as outlined in that previously useful guide - this is now bad info. We really should get some GMs to update that thread.
I've been thinking about a furniture guide for some time now, but some recent threads have put the breaks on that. It's always important to discuss large projects, or at least state that you're about to go skydiving into one.
As always, if you make a page (or pages), put an appropriate category tag on it/them.
