You are protecting against spam right? Or why would you want this? You might try testing alternative question posting options and see which gets a high follow through. Obviously you want some way to protect against spam but by adding as little overhead as possible. You also have captchas in the registration - maybe it's enough.

It was to protect against spam, ensure the user is a real person who can be contacted etc.

But I can see that a few people sign up, post a question, but never click the link so their question never goes live. I may try removing the requirement to confirm emails...

Or give them assurance in big bold letters that their email is safe with you, and won't be published, but is only used to forward answers to them.
