IDEAS for QUESTS should include all the same information that is posted on the list of Open Quests. You'll earn up to 24 XP based on Ideas and Organization. A bonus gift (a virtual item for your avatar) will be given to you if the GM decides to use your submission as an actual quest option.
IDEAS for KINGDOM NEWS ITEMS generally earn anywhere up to 36 XP based on their length and the depth and quality of the Ideas. Longer or especially well-crafted submissions may earn more. If used in the actual Kingdom News, a virtual item will be rewarded as well.
If you submit an IDEA for something else or offer a useful SUGGESTION, the GM will devise a reward suitable for the complexity and quality of the submission.
