This is a sample message you could use to send to a member offering or requesting intangible items:
Dear Freegle member
Freegle is a reuse community dedicated to reuse and keeping goods out of landfill, so your post is not suitable for our Offer and Wanted board.
You could put it on the chitchat section, though, at https://www.ilovefreegle.org/chitchat
Thank you for considering Freegle.
