This new version of SMF includes a new feature to set up automatic subscriptions for things like donations. I just created a new "Registry Supporter" subscription that can be used by anyone who wishes to make a $25 donation that gets you a one-year membership in the "Registry Supporter" group. I'd like to come up with some kind of tangible benefit, like perhaps a private membership forum for more open, uncensored and off-topic discussion, but I haven't yet figured out exactly what I want to do. I'm open to suggestions.
You can find your paid subscription options in your forum profile on the "Actions" menu. I've got it set up to use PayPal, which also allows credit card donations. Please let me know if you try it out and run into any problems.
I'm leaving the old "Registry Supporter" member group alone except for renaming it to "Original Registry Supporter" and changing the group icons so the supporter groups stand out a little more. I don't want to ignore the past contributions that people have made.
