I agree. I think charity events and organizations trying to find help and/or homes for pets should be an exception. The thread discussing the Labrador that was surrendered to ASPCA is not the same as someone putting an ad on here selling Labrador Retreivers for hundreds of dollars that they purposefully bred. Big difference.
Could you allow one representative from Bev's and one rep from ASPCA (and other shelters/agencies in the counties covered in this forum) to have a thread and only post within their respective thread that they start? For example, they could title their thread "Adoptable pets from Beverly's" or "Adoptable pets currently at the ASPCA".
If you are allowing posts about fire department's having charity events or other organization asking for help in the county forums then you should allow the pet charities some leniency in finding homes for these unwanted pets in this forum. It brings awareness that little classified ads will not.
