I know Scottro from the forums. I mention this because I am probably slightly biased. I know that together he and I have spent hours and hours and days troubleshooting and fixing problems that people have reported with the reports mod, adding new features, tweaking, documenting, etc. He's spent a lot more time than I have. I say this because while I agree that people should donate for this great mod, the reality is that people don't.
I don't think that Scott's really looking for a hand out or a pay day, but it sure is nice to make a little money on the side with all the work that we have put into this project, mods, etc. I've contemplated doing something similar just to attempt to cover the costs associated with webhosting, domain registration, etc.
