Since it's become a burning issue (ouch. Sounds painful. I understand that they have medication for that...), I've decided to put the discussion out here.
[ Just FYI, neither I nor R3 are really comfortable with this topic. R1 is, but he's not paying attention right now .... ]
Right now, funds to support Republibot come out of my pocket. Advertising helps, but is not a large or dependable stream of income.
A tip jar has been recommended, but we've been burned very badly by that in the past. If there were a way to do that without risking the site, though, the concept has some merit.
We are opening up this discussion not so much for us (we're not trying for meteoric expansion or anything like that. What we have now works for what we are doing, but we can't do much else.), but because we've gotten several emails and comments suggesting that you guys like us enough to want to help.
We are humbled and honored by this. And it would be inhospitable and ungracious to not accept your offers of generosity (knowing that a good portion will also end up in a charity's coffers as well).
Suggestions for how to make the 'Bot a bit more self supporting go here....
