- Free has three channels and ten queued posts per channel at a time. It is not a ten-post monthly allowance.
- Paid plans charge for every connected channel, including the original free three. Rates above ten channels are marginal volume bands.
- The annual figures are monthly equivalents of annual channel tariffs; the yearly Essentials rate for channels 51+ is $20, not twelve times its $1 monthly rate.
- Paid scheduling is subject to a 5,000 queued-post fair-use ceiling per channel. Prices exclude applicable taxes.
