Today's gift is free online SharePoint training resources. I used these for the first time last week (even though I've been using SharePoint for 15 months).
I have already customised my MySite, to add a wiki for my colleagues, and to put it directly on my home page. And I've linked my SharePoint document library to my Outlook inbox, so that I can see all my documents when I am offline. What I learnt from the training is that I can edit these documents offline, and Outlook will synchronise the changes back to the document library when I'm next online.
The free training is available to download as a complete package from the Microsoft Download Centre, and it is cleverly split into multiple, short chapters, so that you can dip into the section you want.
