Turn off Quick Create

Turn off Quick Create

I am trying to find out how to turn off Quick Create forms. A previous post mentioned that it is under Admin:General Settings but I cannot find it listed there. Also, is there a way to make additional fields required?

I don't want my requestors to submit requests without providing the information we need to contact them and/or solve their problem. It is my experience that if they are not forced to provide info, they get lazy and "forget" to fill in the data.

Thanks in advance!
