I have reduced the amount of questions that you are presented each time.
You now have to (for login AND for each of your first 2 posts):
- enter the letters from the distorted image
- answer one question (this used to be 2 questions)
Depending on your cookies this change may not affect everyone (of those still within their first 2 posts).
Unfortunately the settings for registration and first-post verification are one setting only. So I can not make the per-post questions easier than the registration.
I also do not see an option, to add a message that it is only for 2 posts, and after that you can post with no checks.
