How to implement user donations on my forum?

I own a forum which caters to a narrow interest in a small language, so it will never be huge. However, I still have to pay for hosting and decided to spring for a vBulletin licence last year. So I'm paying a modest sum out of pocket yearly. To help offset this I'm currently running a low level of AdSense ads. This does not bring in much, but I'm unwilling to "upgrade" to big, annoying ads. I'm considering implementing a PayPal donation button. What I'm unsure of are the social dynamics of this.
