is she trying to email her replies to the site ?
cos she has the red star featuer where it all goes into her inbox ...
she needs to make sure she is signed into the right passport that she joined here with . Failing that im not to sure ... maybe she should unjoin and join back up again as MSN comms are a bit like that, ive had to unjoin members that cant get in to a site they then rejoin and the problem is no longer there. It might just be a glitch
