Temporary Member

undefined:

A temporary member is a headmate or similar being inside of a system whose presence there is not permanent.

It is typically used as an umbrella term for several types of walk-ins and demi-members, such as spiribonds/exobonds/etc., modular/fractal members who break apart/reform, a blend who separates back out when the components stop blurring, members who used system travel to briefly become part of a system before heading back to their home system, or anything similar. However, it could also be used as a standalone term for any member who does not/will not stay indefinitely.
