Dear Castle Fandom is a public blog where you can talk to your favorite members of the Castle fandom. You can submit your 'letters' in the ask box, and unless you ask, we won't reveal who it's from. If there is any hate submitted to the blog, the person who submitted will most likely be blocked, and the letter will not be posted. You can send a letter to a group of people, or to a specific person, but you must add their URL so we can identify them.
The blog is based on 'deargleefandom', so see their blog for a 'sneak peek' for what this blog will look like. :)
