Still, it would really, REALLY help if you guys made public some numbers. Like:
- now we have X
- regular maintenance by the end of the year needed: Y
- we wish to upgrade which would cost us: Z
For example, I'll make stuff up: if you have 2500 and you need to spend 500 by the end of the year, then people are simply going to shrug it off, conclude that you have enough for the next 2-3 years and forget about it. But if you add that you wish to spend another 3000 for better servers, which would mean more disk space, more speed and better service, then that's a good call to donate.
And then simply refresh those numbers once a month (because people need to be reminded).
