Basically, this script lets you manage a list of groups (seperate from WLMs own groups) and perform functions such as Block/Unblock and Send Message. I made it because I knew people have been asking for something like this. I know some people may not like the idea of having a sperate set of groups, but it's the most anybody can do for now.
I was not aware of a similar script in the database (by foaly and StUpIdO) at the time this was released
