Have fun! :)
ETA: This (now sticky, yay progress!) post is for questions about how stuff works, e. g. how to tag your post, how to deal with formatting woes, if it's okay to promote your community, etc.
This here entry is NOT the place to look for stories/art/vids/podfic/whatever. I'm not active in this fandom beyond running merlin_finders and can't help you find stuff.
We have a lot of generous members who can, though. After you've joined the community, you can create a post of your own to ask people to find whatever you're looking for (as long as it's Merlin-related).
Please read our rules on posting and tagging before you create any entries of your own. You can find those on our profile page. :)
