There are a number of challenges which have been issued by visitors to the site and on the associated mailing lists. If you are interested in taking up or issuing one of these challenges, please read the rules, and then select the appropriate category from the right hand menu. To assist you, we split fanfiction into the following genres:

General Fanfiction: suitable for all ages. Rated G to PG13.

Adult Fanfiction: Rated 15 or above for strong language, violence and even sex, between consenting adults of opposing sexes. By clicking on the link in the right hand menu, you are stating that you have read and understood these restrictions and have reached the age of majority in your locality. CI5 Operational Control will not be responsible for anyone falsifying such information and accessing restricted areas. At a minimum if caught you will be hauled up in front of Malone.

Slash Fanfiction: 'slash' refers to material featuring or implying same sex relationships. In this context you may assume this means Agents Curtis and Keel, although we in Operational Control have our suspicions about Agents Spencer and Richards. Within these missions, there may occasionally be need for strong language, violence and even sex, between consenting adults of the same sex. Those Agents uncomfortable with the idea of same sex relationships should confine themselves to reviewing other mission reports. By clicking on the link in the right hand menu, you are stating that you have read and understood these restrictions and have reached the age of majority within your locality. CI5 Operational Control will not be responsible for any agents falsifying such information and accessing restricted areas. At a minimum if caught you will be hauled up in front of Malone.
