Hi there, everyone!
After some thinking, I decided to change the system. The followings have been changed:
-You may have as many threads as you want to active. Just try not to abuse it, m'kay?
-No limits about Solo RP threads anymore. You can create two in a row, and don't have any limit for making multiple posts anymore. Again, don't go and abuse of it, m'kay?
-The money system have been changed. This time, the money earned is global instead of only at your place. How it works: Each RP thread you participate in earns you 50 PokeDollars. A solo thread earns you only 20 PokeDollars. That way, everyone gets equal rewards, and it's less hassle to keep track of. Your current amount of PokeDollars changes to this new system, so remember to do the change in your Diary.
