Portal accessibility

Hi,

I am currently testing the ESS/MSS portal EP6 SP2 patch 34 to see if it is accessible for ALL users. Is there anything i chould be doing on the backend side to make it more accessible? I find that there is a lot of feild that are not lable properly and it is basically not accessible for a blind user. My users are working with thye JAWS software. If you have any tips for me that would be very much appreciated.

Thanks
