Problem When Registering

Today, I had a few friends registering on my forum, along with a mod creating another account (because we had a problem and needed another)


In each case, they had trouble registering.


They were all told to fill out the Required fields, and even when they did, it didn't go through until they re-did it many times.

I'm afraid this problem would scare away new members who don't want to fuss trying to register.

Does anyone have the Same problem?
Could anyone look into this?
