Online Comic Archiver
I am quite busy during the day, so I sometimes forget to read the web comics that I do enjoy. That is why I have created a service called CronGrab, which allows me to define certain parameters for a comic website, and then it automatically fetches the comic for me. It has a few layout bugs, and might be a bit tricky to use at times, but it work very well. I have been subscribed to UserFriendly for several months now, and it never missed one. If you want to give it a try, I suggest you read the documentation first.
