I have been asked to set up some sort of change tracking software so that users can subscribe to it and find out when changes are made to my website. I have found free online services for this but wonder if anyone can point me to software that I could buy (or open source software to use) that would allow me to control this a little better. It seems as though the online services don’t last very long so I don’t want to frustrate users by recommending something that just disappears.
Any suggestions would be appreciated,
Jan
