Purpose

In a lecture, people may want to ask questions but not want to interrupt. This script listens to you on a private channel (so it is silent on public chat) and stores your question. At the end of the lecture, the speaker can click on the object and it will regurgitate the questions from first to last.

How to use it

Stick it in an object. The object should appear red; this indicates there are no questions stored.

First you need to set yourself as the 'speaker' - so when you click on it, it will read out the questions.

• Type '/7 setup' to enter setup. From here you can type:
  • '/7 speaker' - to set yourself as the speaker
  • '/7 no speaker' - to un-set yourself as the speaker (for testing purposes)
  • '/7 reset' - (for if it screws up)
• Then type '/7 exit' to exit setup.

Anyone except the speaker can now ask a question: click on the object, and it will tell you to type the question on channel 6.

• Type '/6 ' followed by your question
• To cancel, type '/6 cancel'

The object will say 'Message stored' and will now turn green. You can now ask another question. If someone else is asking a question when you click on it, you will be politely asked to wait.

At any time, the speaker may click the object and it will return the questions one by one, in a first-in first-out order. When it turns red, there are no questions left.
