For threads in the wrong category, you have to ask a mod to move it since they are the only ones with that power aside from supermods and the site
owners. They usually catch it and move threads to the appropriate place when they see them, but sometimes threads slip through.
To put something in your signature go to Member Tools on the tool bar, and click ATS account settings. There is a box there to change your signature,
just don't forget to click submit.
I'm not sure what you mean about not having permission to post a thread. Try typing posts out in word or notepad so they don't get lost if something
goes wrong while posting.
To save youtube videos, I use keepvid.com. The instructions are pretty straight forward and it's free.
Hope all this helps!


Enjoy your stay.
