Mod Block This lists your options, most of you will probably only be bothered about adding movies which is the third option down. The ModCP is underconstruction, atm it is merely a way to verify weblinks. Submit News you probably won't want to use but that's for submitting news articles and info. "Submit a" allows movies, games and series to be added.
Submit News This is the panel i use to add news articles to the frontpage, feel free to use it if you so desire. It uses bbcode, so its just like a forum post. Top block is mandatory, it allows for an introduction to the news, down a bit is the quote, this is where you copy and paste the link. The last box is just somewhere for some extra info or summary. The url box requires the url of the news and the text, although not needed, allows you to name the site it came from if you can be bothered. There's a few areas you can post to, site is reserved for site news (ie. admin), the movies is non-horror news, games is anything to do with gaming, and horror is to do with anything in the genre.
