I came across this one, which sounds exact to what I am looking for, but a little too steep for my pocketbook at this moment - and may just have to wait until I can afford it. (Kind of ironic, looking to implement donation system, but don't have the money to buy a donation system! LOL!)
But I tried searching Paypal, donate, donations, donation and mostly pulled up @Waindigo's add ons LOL! and came across a lot where members can purchase credits and such... but is there any other add ons that my cost less or free that is just a simple PP integration to where my forum could show the buttons to make a donation?
