First thing that needs to be said is thank you for taking the time to post.
As wraith says -- you can use Url Snooper freely without making a donation and without having to wait. The license key you download today will last for 6 months without any limitation in the software. After 6 months if you still like using the software, you have to visit the page again and download a new license key. 6 months after that, if you still like using the software, you will be given a license key that will never expire and you'll never have to come back again.
We know this is unusual, and maybe it sounds complicated. I know it can seem annoying and frustrating, especially if you are like me and don't want to have to be bothered with silliness when all you are interested in is finding a tool to do the job.
I just ask that you try to understand where we are coming from -- while the rest of the internet is making money off of advertisements or selling commercial software, we are trying very hard to make our own way in the world by building a place where people can pay what they want to directly support the continued development of software.
Ironically, and tragically - it turns out that while many people seem to have no trouble paying for software that they can't get free, few people are willing to contribute money to a software project unless there is some compelling reason to do so. We are trying hard to find a way to strike a balance -- to keep our software free and easy to use, but at the same time find a way to reach people and explain how important it is that we have their financial support *if* they like what we are doing and can afford to support us.
