Well, welcome to :SF ^_^
I highly suggest you both make your own accounts though as it's actually against the forum rules (Rule 2 bullet 6 -
Use by more than one person of the same account - friends and partners are required to create their own account, no more than one person is permitted to access this site via the same account.)
to have more then one person use the same account.
Try not to make any lengthy posts with nothing but text speak, if your phone has a full keyboard, please use it.
