Add username front off login and tools

Hi,

I would like add a line of text with the username of the user after he logged front off the text "login and tools" on the top right template. Like this for example :

Hi, John DOE Login I Tools

What code and file I must modify on the template ?

Thanks.

Hi Gavick Team, there is no reply for my topics ?

I'd like this too...

Love to know how to get this done as well.

Thanks
