I think it's a good idea to read this quote from the site DonationCoder.com:
Greetings , and welcome to the DonationCoder.com License Key page.
All of the software from DonationCoder.com is free. You can use the full versions without any limitation, and no payment is necessary. The reason we require people to download a license key from us is to get them to take a look at our website and think about whether they might be willing to make a donation to this site.
In order to encourage people to really consider making a donation, we have adopted a somewhat unusual policy for people who do not donate:
The free license key generated here will remove the reminder nag from the program for 6 months.
After 6 months the reminder will come back and you must return to this page to generate a new license key which will last for another 6 months.
After 1 year from your initial signup you can return to this page for a permanent non-expiring license key.
If you're not ready to make a donation at this time, but want to download a free key for one of the programs on this site, you'll first need to sign up at our forum, or log in if you already have an account.
And if you don't get this key you see the reminder nag constantly.
Not for me, but thanks anyway.
People laugh because I'm different, I laugh because they're all the same.
