[Qgis-community-team] git trouble

[matteo]

Hi guys,
I have a question about git.....
There has been added a branch (manual_en_v1.8) so I tried to update my 
repos (both cloned and forked). But I'm not able to update my repos with 
the master one..
On my github doesn't appear the new branch (I have still only 5 branches...)
Could some git-guru of you write a short howto for how to update 
correctly the cloned and forked with the master one?

Thanks guys and sorry for my ignorance...

Cheers

Matteo
