To be able to monitor several SVN repositories, I have to check periodically using any SVN client toole. Of course this is not a good solution. As a better solution I installed SVN hook on each repository to send me an email on each commit. It works good, but some of the repositories is from other sources that I have no control on it.

I found CommitMonitor tool which you can register any number of SVN repositories and it will periodically check for new commits and will report it.

I tried the tool and found it easy to install, configure and use. Look at: http://tools.tortoisesvn.net/CommitMonitor
