If you require a certain level, then your moderator will ask you if you want to evolve your Pokemon.
If your Pokemon needs an item, your moderator will again prompt you for evolution. If it requires an item and a certain level, then be patient, it will happen.
Time of Day:
If your Pokemon needs a certain time of day + anything, make sure you put the time of day in your post. Like, "The mood was high in the sky."
If your Pokemon needs to be traded, you don't need to trade it. Just make sure you tell your mod In character in your thread what you need and they will work it out. Don't worry, we're here to make all this easy for you.
