This type of enquiry is tentative, and may not be included in early versions, as it could pose numerous challenges specific to this type of enquiry. As there is no specific organisation involved, there will be no legal restrictions on what can be required, but the general rule is always: the more you require the less chance there is of finding people to fit the requirements. This is naturally self-correcting.

• Features: learning, life; low commitment
• Parties relate diversely: people take on predefined roles which may be the same or different
• Required questions: which game do you want to play, and in which role or roles?

Example motivations for using this type; people who:

• want to participate in an informal group of other people to share something
• want to make music, self-organised, with other people

Only if they are independent of the role chosen:

• Gender
• Age range
• (Membership of specific groups)

• Experience of playing the role
• Skills necessary for playing the role (at the required level)
• Possession of any equipment needed to play the role
• (many other things could be required, depending on the role)

• Time constraints — this requires addressing separately
• Location (if playing requires physical presence) — general or specific
• Type of play, if there is a commonly understandable scheme
