I've decided against lifetime subscriptions for Pagecord (at least for now). I'm going to add a pay monthly option instead. The cost will be a bit higher ($4/mo) but some people out there are only comfortable committing on a monthly basis.

One thing I've learned with Pagecord is that a good chunk of customers like to experiment with all the blogging apps and switch between them on a frequent basis. Maybe monthly will work better for them.
