Requester is taken to the "Home" page when logging on

We are new users of Zoho Managed Service Engine and have recently set up our customers as Requesters and our support staff as Technicians.
 
When one of the requesters logs into Zoho he is taken directly to the "home" screen and not to the normal screen where he can view his requests. He cannot go back to the request screen as he says there isn't any option to close the home screen down. This is preventing him from being able to raise new requests
 
I have checked his user profile and he is linked to a site, a department and allowed to view all issues for his department.
 
Does anyone know how to resolve this problem?
 
Thank you in anticipation
 
Elaine
