Alright here are the rule's you must follow to trade safely in this forum:
1. If you offer one certain pokémon, make sure to trade that exact pokémon to avoid a big problem.
2. Cheating while trading is not allowed. You will be banned if you do. Example : Tricking other members to believe they are getting the pokémon you promised to give them and then when the pokémon arrive at their side it's a fake pokémon.
3. Do not waste the time of other members while trading for example : Do not disconnect while trading, Do not stay frozen when your trade partner is waiting for you, Do not call your trade partner a hacker if you spot any hacked pokémon on his team that has nothing to do with you 'He might have his own reasons'
For so far this is enough.
I hope you understand this rule's while trading pokémon with others. :)
