Hi, My name is Yaron Shahrabani and I translated the Mantis Bugtracker into Hebrew.
 
The difficulties the user might experience are:
- The pages will display from left to right instead of right to left, same for the e-mails (Suggestion followed)
- The users might experience difficulties on submitting Hebrew text to the server
 
 
My suggestion is:
- Adding the following to the HTML tag
    Instead of
        <HTML>
    There should be
        <HTML lang="il" dir="rtl">
 
The closure tag is the same
 
As for the e-mails I think this solution may also work for e-mails
The Hebrew submision is the main difficulty here but I trust on you about it because I have no idea...
 
Best Regards,
    Yaron Shahrabani
