After account creation and login, you can change your user preferences and settings (click on the link Settings at the top of the page).
The default values should be fine for most of the preferences, but you might want to change:
- the time zone (to convert the UTC time to your current time).
- the size of the editor input box (depends on your screen resolution and font preferences).
- maybe the preferred language (not necessary with a correctly configured browser).
Then click on the save button at the bottom of the page.
