I posted my first thread but has disappeared. Says its awaiting approval? Is this to prevent spam and how long does it take to get approved?

Some threads get put in an approval queue until a mentor can look at it. I'm not sure exactly what the criteria are.

I only glanced at your post, but I think you implied it was original research. PF doesn't accept original research (this isn't the place for it), and that may be what's caused it to need approval.

Your post has been deleted. We do not allow personaly theory discussions here at PF. Have a nice day.
