In your own space, post a rec for fannish and/or creative resources. Leave a comment in this post saying you did it. Include a link to your post if you feel comfortable doing so.
For HP stuff, I tend to use the online lexicon and a variety of other things. Usually it just depends on what I’m doing. I also got the official creature book for Christmas, which I plan on making good use of. I use RP character sheets sometimes, but mostly when I write characters I’ve played before.
For Star Trek and other things, I have an old RPG book, plus there’s a ton of online resources. Same with a couple of other things. I do so wish I could write my epic Star Trek reboot AU. (Yes, an AU of an AU, lol). For my Honor Harrington fangroup, I use the online wiki, the resources, the group gave me, and the god called Google.
For original writing, I tend to use my research – for my Regency work , I have a plethora of links that need to be organized someday. I also use some images, poems, songs, all sorts of things. A lot of my titles come from songs. I just wish I could write something sufficiently long to call a novel or something.
Sorry I don’t have anything concrete. I’m tired, and it’s been a long day.
