Awesome read so far! I have a question though: my current code does not want to distribute any of the tokens in response to Ether transactions. I've sent a few Ether from various test accounts to the contract, but the contract won't send any of the tokens back. What am I doing wrong? My code:

Edit: The Ether also seems to be stuck at the contract address and is not being send to the address that has created the contract.

pragma solidity ^0.4.4;

contract Token {

function totalSupply() constant returns (uint256 supply) {}
function balanceOf(address _owner) constant returns (uint256 balance) {}
function transfer(address _to, uint256 _value) returns (bool success) {}
event Transfer(address indexed _from, address indexed _to, uint256 _value);
}

contract StandardToken is Token {

function transfer(address _to, uint256 _value) returns (bool success) {
    if (balances[msg.sender] >= _value && _value > 0) {
        balances[msg.sender] -= _value;
        balances[_to] += _value;
        Transfer(msg.sender, _to, _value);
        return true;
    } else { return false; }
}

function balanceOf(address _owner) constant returns (uint256 balance) {
    return balances[_owner];
}

mapping (address => uint256) balances;
mapping (address => mapping (address => uint256)) allowed;
uint256 public totalSupply;
}

contract JIMI is StandardToken { // CHANGE THIS. Update the contract name.

/* Public variables of the token */

/*
NOTE:
The following variables are OPTIONAL vanities. One does not have to include them.
They allow one to customise the token contract & in no way influences the core functionality.

string public name = 'JIMI';                   // Token Name
uint8 public decimals = 0;                // How many decimals to show. To be standard complicant keep it 18
