Linux

Hi all Im Linux newbie and love it! Mandriva.
As with Windows their are common things we do daily or frequently: updates, security updates, and more updates, check pop mail thru mozilla, check news feed rss thru bittorent, ect..

So my question those steps thru windows are easy acessible, Im used to doing it! Being new with Linux Im looking for what you almost commonly do on a daily basis, I'm sure the above apply but Im lookn for more detailed steps incase i miss something later down the road.
Thanks much, Cheers
