Hero Points

I am not going to set hard and fast rules, because everyone wants something different. My way of tracking followers has no trouble with this. I will modify this as needed. This page serves to keep a sensible ruling on hero points and follower points.
== Hero Points ==
A hero point can be spent after making any d20 roll, before the result is known. You then roll 2d6, and add the highest to your result.
Clarifications:
* You can only use one hero point per roll
* You cannot hero point a roll against a known DC
* You cannot hero point a roll made against another PC (in the cases of interparty conflict)
== Town Points ==
A follower point can be spent in a number of ways
# By rolling 2d6 and multiplying the result by 1,000. That's how much XP you have to spend on your followers, in any way you wish
# By rolling 2d6 and multiplying the result by 1,000. That's how much GP you have to spend on trade goods (notably building supplies). Trade goods normally sell for 1/10th of their buy price, so this is no more valuable than option 3. See this list: http://paizo.com/pathfinderRPG/prd/ultimateEquipment/gear/entertainmentAndTradeGoods.html#trade-goods-table
# By rolling 2d6 and multiplying the result by 100. That's how much GP you have to spend on anything follower-related, such as mounts, gear and labor.
==== Clarifications: ====
* You may spent a hero point as a follower point, but not the other way around
* A "follower" is anyone you've gained through leadership, or any of your hanger's on. It does not include cohorts (although they're automatically excluded by the next rule).
* All followers gained through leadership automatically accrue xp at a slow rate, independent of this system.
* The max HD someone can have by this system is equal to three less than your character level
* You can spend the xp on any of your followers ("Level up this group until they're all level 4") or on one particular person ("Make Crusher the horse he was always meant to be")
* Buying a new follower means you pay whatever their experience cost would be based on their hit-dice (for player races) or CR (for monster races) plus an extra 1,000xp. 
** A CR 7 creature would cost the same as a creature with 7 hit dice, namely 35,000xp+1,000xp. 
** This means a new 1st level follower costs 1,000xp as they do not have any experience of their own.
* New followers gained in this way count as followers granted by the leadership feat - they follow you out of respect for your heroic deeds, and do not need paying.
* Monsters with class levels obey the rules here
