I really love how you've used the metaphor of a revolving door as the members who are on this site. It's very punchy and well written in just thirteen words.

Some of those ghosts do seem to become more substantial somstimes, don't they?
Perhaps we should all be grateful for the site's seeming ability to recycle!
Clever write, Helen.

ghosts are spirits
lost in time and space
new members don’t seem lost

Revolving doors puts ma heid in a spin......
