You will be surprised how many people are happy to help if they have high hopes for your projects.
Getting donations from your forum members will only work if you have those that are generous when it comes to supporting one's project. Not many people are like that. It's why you don't make donations your main monetization target.There's no harm in trying especially when there's a chance to get some people donating to your project. I think making use of GoFundMe is another way to get money from donations to sponsor your project.
From my experience, a lot of people don't usually find it appealing to donate. It is only a few people that feel like supporting a project once in a while that donate.Are donations a good way to monetize your project? How well do you implement such strategies? Were they effective?
