Hi, -] I suppose the username/password for Squeakmap and Mantis are the same, is it so ? -] I would like to make a Squeakmap package for STON but I have issues logging into Squeakmap. I made a user, username "NMI", but I never received the confirmation email. All attempts I made to re-login or rewrite the password failed. I guess something is wrong. bye Nicola

Hi Stefano, this is the problem I saw too. My guess is that it is a simple encoding bug somewhere.
