This is a great little website - well quite a big website in that it has had over 2 million followers a month. It's pitched at film school students in the US but also includes festivals and opportunities for international film makers - and it's nicely designed too which is a bonus and worth a read if you need a break from that editing suite or from working on your script.
Enjoy. http://nofilmschool.com/2014/06/money-filmmakers-grants-part-ii-summer-deadlines/
