I am putting in a subscription to help offset some of the costs for the hosting.
There are four levels:
Free - This is what everyone has now. No changes to this.
Bronze - $1/month or $10/year. Get a spiffy badge.
Silver - $2/month or $20/year. Get a different spiffy badge.
Gold - $3/month or $30/year. Get the spiffiest badge.
One-time donations get a badge with the year on it. I will probably backdate this one to include the 2020 donors.
All the badges can be seen on your profile as well as four displayed on posts.
To get a subscription, go to your profile, and under Actions you should see a Paid Subscriptions link. This will take you to a page showing the various subscriptions.
