It is never easy

Mom spent the better part of the afternoon with cablevision/Optimum to set up her email.  She feels she isn't getting it and they todl her she is.   I tried to access my email (didn't really register yet) but Bob got the router yesterday and says that I will hve to sign in with the password he gave me (no I won't share it) but I htink he may have left out some information.  I tried it and don't have an email account.   I asked Mom if I have to sign on under her email or account or what.  We are both too tired tonight to figure out what we are doing wrong.
