Ok it was my suggestion so i will answer but if someone that has a big part in it, who helped bring it to life (Someone who abuses their Meta privileges) Has changed my original rules they can edit this ;).
Ok in my original rules you battled any gym leader in any order (Only one battle a day)
Im not sure whether that still stands but i hope it does.
But only when you have beat the gym leeders you can go onto the elite4 the elite 4 are in order and very few will get there if any (excluding Pb)
Once you have beaten the elite four (Congratulations btw) You battle the champion, if you manage to beat the champion (which is not easy at all) You get a badge for all your merits on top of the badges you originally have and become the 9th gym leader.
