When roleplaying with your dolphin, there are a two important things to note:
1) They cannot speak long sentences.
2) Their speech is imperfect.

Once you are admitted to the craft, you have to make your dolphin. There is a parent #758.

Your dolphin must have its race set to dolphin. If it isn't, please +mail Jeyinshi with the dbref and we'll get it done.

After your dolphin has been filled out, it must be checked over by the current staff and approved. Basic things such as desc and enter/exit messages will be looked at. Once it has passed examination go play as much as you want!
