how do I edit my profile.....

[Jerry4000]

A few years ago I joined the Community Sculpture site....but lost my username and password...
soooo...I generated a new one a week ago...and I can log in but I couldn't open a new topic...
since last week I found my old ..username... and password...and it works..enabling me to open this topic.the problem is is that I have a new email address and don't know how to edit my profile...and if I do can I use my new email...which is probably in the system with my new name and password.
