A serious (really) suggestion
A lot of non-profit organizations that want to encourage donations make a practise of somewhere (on a plaque or in their newsletter or whatever) publishing a list of donors. Although amounts are almost never listed, the donors are sometimes divided into categories (like "supporting members", "angels", "patrons", etc.) depending on the amount of their gift. Usually they are also broken down by calendar year or some other unit of time...so, there would be the "patron" list for 2002, but that person would no be listed for 2003 unless the gift were repeated. I am sure we are nearly all familiar with this sort of thing.
Maybe UG could do the same for hobbyist contributors - it would presumably be easy to set up a category with restricted posting rights for these lists and to give them some appropriately humorous names (e.g., UG kiss asses, UG total suck ups, ...; no doubt C9 could come up with something better).
I'll bet it would encourage contributions. Of course, any donor who preferred not to have his screen name listed could indicate that he preferred to give anonymously and be omitted. Actually, why not include providers who make donations as well.
There is probably something dumb about this idea, but after a long day of intense meetings, I can't immediately see it.
