To play Kriona, you must first create an account. This account lets you post on the forums, chat with other people, or log issues in the issue tracker.
Next, you create a character. Your character name is the same as your account name. If you want to play multiple characters, you are encouraged to create multiple accounts!
When you are finished, begin your story to start adventuring. You can adventure with your friends, create multiple characters and play all of them at once, or go on a solo adventure.
A secondary course of action is to ask for help in the Global chat. You might get a more immediate response, but the people who know the answer may not be reading that channel.
Your best course of action will be to search the Help! board. If anyone has had the same question in the past, you will be able to find the answer.
If you can't find your answer there, you can post asking for help.
