Header and stylistic changes

The header of the blog has been changed:

- Main changes are in #blog-header and related to it.
- Margins also have been changed.

Later, will make corrections with colors of the blog. For some reasons, I like this nasty green one :)

eCalendars

Google has launched its latest product against existing ones such as Yahoo and Microsoft, unveiling a free online calendar service -- Google Calendar.

Also, I've discovered AirSet and started to use both of them. Should provide a comparison. But seems that AirSet is more comfortable...
