A new more small changes

[RSS new | Brush Pen — Nib and Tip Geometry]

The last updates for this month are as follows: * Better looking emails. Hopefully, these will help with the emails not ending up in spam as often. * Backdating of usage records. On the [usage records page](https://www.fountainpencompanion.com/usage_records) you can now add usage record entries for past days for active and archived entries. * Users can now delete their accounts themselves. That's essentially just a self-service tool that makes my life easier.
