Change masthead text away from welcome - homepage framework not working?

Hi,

I've trawled through countless threads without getting a clear understanding on this...

I'd like to change the masthead text from Welcome <username> to Hello <username>

I thought I could do this by changing the text for the Header in the homepage framework (SAPDEFAULT) but someone in a another thread mentioned that this change doesn't work on later versions - not sure if they mean't portal of backend (we're using NW7 and ERP6.0).

Can anyone advise what's the reccomended method for doing this?... or should the homepage framework change work?

Regards

Phil
