 # IF YOU DON'T READ THIS YOU MAY RENDER YOUR USERFILE USELESS LATER
 # Eggdrop encrypts its userfile, so users can have secure passwords.
 # Please note that when you change your encryption method later (i.e.
 # using other modules like a md5 module), you can't use your current
 # userfile anymore. Eggdrop will not start without an encryption module.
