Reblogger
http://jsoft.ca/reblogger/

Reblogger is a comment system for web logs that is designed to work with Blogger blogs and other systems as well. It can be used as a remote commenting system (for those without cgi capability), or can be installed on any server with CGI capability and perl. Following are specific features of the software: It allows multiple users, i.e., people can add their own reblogger accounts on to user’s server. If someone doesn’t have a CGI enabled web server, they can host their comments on user’s server. If there are extra resources the general public can be allowed to host their comments on server. The template that it uses is like a Blogger template, where special tags can be used to indicate where to put the comments, how should it be formatted and where to put the form to submit a new comment. The software provides the facility of email notification. Reblogger can be set to send an email to user whenever someone leaves a comment on web log.  One of its features includes removing unwanted comments/ offensive comment.

It can also help in IP Blocking. If someone is continually harassing the user, then he or she can block their IP address. This will restrict them to from commenting. HTML in comments: it allows usage of <b></b>, <i></i>, <u></u> and <a href=""></a> tags in comments. Also, links are created automatically when URLS are typed in a comment. Time Zone can be selected by the user to have the time and date that is displayed adjusted accordingly. Installation of the software: Installation can be easy using Linux/Unix or Windows/DOS. The archive run the file called "install" before the installer ask some questions to get an idea about where on server reblogger will reside. The URL of the website is entered where reblogger is installed. Start with http://. In most cases CGI scripts can only be run from the CGI-bin directory. So, here the user needs to specify the path to the CGI-bin. If there is no CGI-bin, then change this to something other than the default (try /reblogger/). Otherwise you probably won't need to change this.  This allows the user to specify where important things, for example: password, are to be stored. The software uses sendmail to send any of the emails it needs to send. Once this information is entered the installer will try to figure out what the web address of the reblogger directory is. The installer will then show the information entered. If everything is right enter "y". The installer will now ftp reblogger to user’s website. The reblogger is ready to use. Now that reblogger is installed, a user account should be created. Once account is created the user is taken to the comment manager, where he can customize the settings. Reblogger can be used by just one person for one blog, or one person for a few blogs, or by many people for many blogs. Users can allow as many people as they want.
