Can anyone give me the basics on filling out a D and D character sheet?

First, you need a Player's Handbook. This contains the races, classes, and other information you need to create a character. Also, if you have a specific character in mind, you may need additional rule books. For example, the character I play as is a Grimlock Samurai. This requires the "Hordes of the Underdark" book, which has the race details for the Grimlock, and "Complete Warrior" which has the class details for Samurai.

1. Create a name for your character.

2. Decide your character's Race.

3. Decide your character's Class (you must choose the Race first because some Races cannot be certain Classes).

4. Decide your Alignment.

5. Roll for your base stats. This is detailed in the Player's Handbook.

Hope this helps! Feel free to contact me if you want to play over the internet.
