Where in the world does Alstrasoft get off comparing this script to Aweber.com and Getresponse.com? It can't even handle a double opt in set up! The script has many flaws. 404 errors abound! There is NO User Guide, Tutorial or FAQ. Support is poor, does not address your questions directly, and stops communicating with you the minute you mention "refund". BUYER BEWARE. STAY AWAY!
