My Profile on Careers Portal

My Profile on Careers Portal

When a potential candidate is using the careers portal, signs in and create his profile. The system display the pop-up alert we have created saying thanks for applying for this job. It also sends out an email to the candidate owner saying this peron has applied for a job. basically lots of alerts being sent when someone is only creating their profile not applying for jobs. Any ideas what to do - this is going to get quite confusing. Thanks, Stephen
