Software function is to loop through each member of a group and send a private message to every group member only once in a 3 second interval. ("sends a message to the first user in the group ... waits 3 seconds .... sends a message to the second user in the group ... waits 3 seconds ... etc"). With the option to skip specific group members.
The software needs to have an input box for the group page url, and a button for to extract each member in the group.
After it has a list of each member in the group, the members need to be displayed on the screen to the left in alphabetic order, At this time you can select select which members to remove from that list and click a button "Delete member" which will take the member off the list.
After that there needs to be a textbox for the user to type a message which can support plain text and urls.
After you have typed your message out, There needs to be an input box for how many seconds to wait before sending the next message (3 seconds).
If a message can not be sent to a group member it will need to skip that group member and continue on to the next group member in the list.
Once the program has sent a message to each group member it will need to display a list of each group member it has successfully sent a message to and a list of each group member it failed to send a message to.
