Send Email to Certain People in Group

I am interested in sending a message only to those who meet a certain Role inside of a group on Second Life. For example, only the merchants. How would I go about doing this, or creating a script for it? Any help would be appreciated.

By the way, this is sort of a double post, since I believe I asked in the wrong forum.

There's no way to identify people by role within a group, so you'll have to create a mailing list within a script. There are several options. If the list doesn't change often, you can hard code the keys for members in the script itself. If the list does change frequently, it may be better to keep the keys on a notecard that the script reads each time you want to send a message. To get a feel for list functions, take a look at http://wiki.secondlife.com/wiki/Category:LSL_List. To see how a notecard reader works, look at http://www.wakatech.com/articles/lsl-scripting-basics/configuring-lsl-scripts-using-a-notecard/.
