Hi, I'm looking for freeware that will allow me to monitor
web pages for changes, and will alert me to those changes.
Something along the line of Watznew, Website Watcher,
Webspector, etc., but free. Any one know of anything?
The program I'm currently using is "WebMon" -
http://www.markwell.btinternet.co.uk/webmon/
Same sort of thing as c4u - doesn't have the nifty 'preview'
bit, but (from memory as I haven't used c4u in awhile), it is
more stable and does have filtering capability (ie, monitor for
changes from xxx to yyy in a page).
One difference is that there is no 'tree' structure like in c4u
- all the pages are lumped together, but I found if I name
entries carefully - eg precede all programs with "Program", such
as: "Program Webmon", "Program XNews" etc, and other things with
other designations then let the program sort by status or
alphabetically, it works ok and is just a minor difference.
One bonus is that it is actively being updated the author is
really nice and helpful.
I used to use "Check 4 New", but then it went adware - The
author claims that the next version will not have the ads, but
he hasn't released this version yet and it's been a couple of
years, it appears that development has stopped entirely. I did
email him some months ago and he said that due to a computer
crash he had lost everything and decided to rewrite the entire
program from scratch, it looks like he decided he couldn't be
bothered...
Anyway, those three mentioned - C4U, and WebMon being the two
freeware ones, are the only ones I've tried and they all have
their advantages and dissadvantages. I think it's just a matter
of trying and seeing which one you like better.
Oh - one always handy bit of info - if windows crashes and you
have to reset the computer (Webmon doesn't cause this but I have
other programs that do

WebMon seems to go back to the state
it was in the last time it was sucessfully closed - ie, you will
lose changes in webpages detected the last time the program was
open. Just thought I'd mention that, since it is something I
like to know about in software that isn't often reported.
