When working in the middle of a presentation, how do you play the slide show starting from the first slide? check all that apply.

at the bottom of the screen you can press the play button but i dont know what the choices are.

to change your username, you must:

1) make sure what the username you want to change to is allowed in this community

2) contact a administrator (for example, jaysl)

3) through pm, tell the admin what you want to change to

4) if the username is allowed, it will be changed in a matter of seconds (minutes at most)
