Hey, I'm a "sustaining contributor," but I still get bugged by ads when I do Mudcat on my phone...But for many years, Max has been able to keep Mudcat out of the financial problems that once plagued us. Once upon a time, I'd send Max a thousand bucks a year, and many people worked hard to gather other contributions - and yet we were still behind. We still need donations. But for many years now, Mudcat has been financially stable. Most of that is due to Google ads. The ads can be annoying at times, but they pay the bills.
