I noticed no one has said anything about pokemon abilities, such as static or run away. I realize some of these require a random chance not able to be done normally in rp. so here are two suggestions on how.
1. Every pokemon must have the ability given to it by one of the games, for example, Pikachu would have Static.
2. Make a dice roll. Its rather easy. Go to the administration panel and select Modules> Dice roll then add a simple 4, 6, 8, or 10 sided dice. Then you will get a widget on the bottom of the post when posting a reply (wont work with a quick reply unless you know the BBC code for it) and viola.
Again, just a suggestion.
