Code:
python sendpayment.py -C -N 4 <wallet> 0 <address>
The script put the transaction together, and presented me with the options and a "y/n" prompt. I pressed "y" without paying too much attention and ended up paying some asshole 2.8 BTC to send a little over 5. Which is more than half of the bitcoin controlled by my privkeys.
A couple suggestions:
1. Kick those people from the IRC with 50%+ fees.
2. Present the cjfee in something other than satoshis or have an alert that says you're about to pay an insane amount.
