Normal withdrawal is free and takes 30 days. The advantage is that you'll
also get a percentage of the fee-pot added to your withdrawal (see rules section).
Go to the Contracts screen, click on the Hodl contract, under "Select Function", pick "Withdrawal Initiate".

The "Execute From" account should be the address that has the Hodl tokens
Once the transaction is sent, that will lock your tokens for 30 days
Send Ether should be 0
Do not attempt to transfer any tokens, add new ETH or withdraw during this time, the transactions will fail

After doing the "Withdrawal Initiate" function, here is how to check how many seconds left to wait:
Enter you address in the "Withdrawal requests" input field.
It will show two attributes: "Since Time" and "Amount"
Use the "Since Time" number in the following calculation:
SecondsToWait = SinceTime - CurrentTime + 2592000
(CurrentTime is the unix timestamp of the current block) If the resulting number is 0 or less, congrats - you are ready to complete the withdrawal (and take some fee-pot)!

After waiting for about 2592000 seconds (30 days) you can complete the withdrawal (and take your share from the fee-pot!)

Go to the Contracts screen, click on the Hodl contract, under "Select Function", then pick "Withdrawal Complete".
The "Execute From" account should be the address that has the Hodl tokens
Send Ether should be 0
