The full feature set has expanded a little:

Anti-Brute force (lock after 5 invalid attempts). Unlock button available when logged in

Email notifications to the admin when a user attempts to entry

Email notification to new users with their code and entry restrictions

Geofencing

Entry scheduling

Access expiration date

Entry count limit

Logging for all attempted entries

The email templates and smtp server info will have to be edited manually, as I have little interest in adding all of those fields into the website settings page.

Side note: Sparkfun is out of the solenoids, but Digikey also stocks them for the same price from Sparkfun.
