In your own space, post a rec for fannish and/or creative resources and spaces. Tell us where you go to dig up canon facts for your fandom, or where you get all the juicy details about your favorite ship. Where do you like to hang out and squee like a squeeing thing? Leave a comment in this post saying you did it. Include a link to your post if you feel comfortable doing so.
Honestly, Google is my absolute first go-to, unless I know someone else who has the answer. For Harry Potter, I generally go to the Wiki anymore, though you have to beware interview and Pottermore info. If I don't want that, I'll still go to the Lexicon. Sometimes I refer back to the books, of course.
For others, there's generally wikis even if I don't know them off hand, and google helps find them for me :)
