The simple way is to roll a D20 and add the Attribute bonus (or subtract) plus ½ your level. Every 4 levels you get to improve one attribute by 1. The higher the roll the better the result. Some tasks have a difficulty number. The game master may require the Player to write a good character history to determine background skills.

Backgrounds as Skills
Instead of a huge complicated skill list you just make up a background and from there you get your skills. For instance if you say your character was raised on a farm he would have the knowledges that a rural farm boy would have such as tending to crops and animals, barn building, and a few wood wise skills as well. A city dwelling character would have different knowledges as well. The game master will be the final decider on what a character can have as there will always be the player that tries to great at everything. Give anyone wanting a background as such many troubles that such an adventurous background would give.
Hope to soon have a file hosting site to use.
