Great hack! but i have a question before i install:
If i set the "Hide blank fields notice" to "show every x days" and a user then enters in the box 999999999999 days. would he be able to do that?
Another thing is a suggestion, i think you sould add another option, maybe the administrator can decide that a specific field is so important that it must be filled, otherwise the user can't post posts, can't read threads etc. before the field is complete?
I'd like to here your response, Thanks in advance
