Welcome to the forum and congratulations on your new tablet . Nice of you to become a member of Android Tablets.
To get you started, I'd suggest you click this link to the Android Tablet Q&A section. Read the "Sticky:" threads at the beginning for some good general information about tablets and Android.
If you need help specific to your own tablet, look down the main forum page http://www.androidtablets.net/forum/ to find the forum for your particular tablet and start a thread there asking whatever questions you might have.
If you can't find a forum for your tablet or you aren't sure which tablet you have, the Android Tablet Q&A section would be the place to go for help.
