this program is so easy to use and does exactly what i need it to do. i use it to monitor websites for classes that i want to take in school but are already full. subscriber tells me right when there are openings so i have an advantage over the other kids. i was having problems with figureing out the html code to use so i would just be alerted when a certain class section opened. the tech support was so helpful and responded to my email the same day. they rock!
