Greetings! I'm Velris. If you want help learning about D&D, I can definitely give you some. I've been playing the 3.5 edition of D&D pretty much since it came out.
Pretty soon I'll be starting a game set in the world of Eberron, which is one of the pre-made campaign settings endorsed by Wizards of the Coast (The company that produces the D&D game).
Character sheets in this guild are handled by online sheets such as the ones here:

Dice rolling for in-game things is handled in the campaign Play threads, while dice rolling for character creation is handled
here.Anyways, if you want to learn D&D, I'd say join my Eberron game when it starts. It'll be starting from level one, so there'll be plenty of time to get used to the game.
