She could set up a PyPal account specifically for The Pet Food List, and we can donate via PayPal. It would help if we put our forum user name in the special notes section of the payment.
Many forums I belong to have special priviledges for contributing members. The first would be a special status notation like "Supporter" instead of "member" or "newbie" or whatever it says now.
Another perk is to have special private forums open only to contributing members.
Other perks are discounts from sponsors. Perhaps Kumpi or Back to Basics, since they post here, would like to offer a 10% discount to contributing members, or free shipping.
Maybe Pet Food Express can offer a 10% discount. (That would help those of us in Northern California.
) Maybe a discount on Pet Sitting from PetSitUSA members! (I sure could use that!)
Maybe people could donate pet-related goods, and Therese can have a raffle for contributing supporters.
