There's many ways to help and money is just one of them. Seeding the torrent is extremely good as well.
As for donations, you can look at this page to give an idea on how much other people donate:
The idea behind financial support is that I can leave my job and work full time on the distribution, and then start to hire other people (artists like Niksa and Carlos, support people like Husse or Scorp123, developers like Lars.. people who currently bring a lot to Mint but only in their spare time).
At the moment the toal income represents approximately a 1/4 of my own salary, so we're far from hiring anyone or me going full time on it, but it makes it easy for me nonetheless to dedicate more time to it.
It's entirely up to you to decide whether you want to donate or not. You don't have to and there's no problem with not doing so. People contribute in their own way and sometimes a suggestion or a piece of feedback can be more valuable to us than a donation.
The best form of income for Mint is the sponsoring, because it brings us a regular and predictable income.... exactly like a salary
At the moment we have 4 sponsors and together they make a salary of $12/month.
Again it's entirely up to you to decide how much you want to sponsor Mint, and if you do. If you want to make a financial contribution to the project I strongly recommend you become a sponsor. If we have a lot of people sponsoring the distro, even if it's a tiny bit it's a tiny bit per month.. and it adds up, this basically mean we can make salaries and pay people and hire them.
