My name's Taya, i'm an admin on The 100 Wikia. I saw you listed as our affiliates so I thought i'd contact you. I did just notice however that we're not listed in your affiliates, so maybe that has been a glitch.
Regardless, I'd love to talk to you about a concept we came up with, called 'CW Family Week'. In that week(s?) we'd promote sibling or family relationships all over the network ( The100, The Vampire Diaries, The Originals, Arrow, ...). We wanna do this to encourage people to support the show (even during hiatus) and that way we can unite our own fandom while also endorsing people to watch other shows that also have great family dynamics.
What it would mean is that we (for example) have a family page (in our case for example the Blake Siblings, in yours maybe the Salvatore brothers) as our featured article, we encourage people to make fanarts and edits and we could also try a trend on twitter, among other things. For us, this project could tie in with The 100 Promo Project, our hiatus project we set up to get people to watch the show starting S3.
We chose to focus on family because that seems to be something with the least trouble over. I think there'll be less drama then if we have say a ship-week. We hope you consider doing a collab with us over this and ofcourse this does not have to be limited to wikia. We can have all sorts of fandoms on the CW shows involved. The more the better!
