## Understanding the claimAll function
The steps on EOS.IO website suggests you select `claimAll` to claim your ERC-20 EOS Tokens.

This function essentially runs the `claim()` function in a loop for each contribution period that has ended. And each time it executes the function it needs gas. This is a screenshot of me claiming my tokens at the end of Period #2 when my only contribution was during Period #0:

As you can see it has also tried to claim EOS during Period #1 and Period #2, returning with 0 EOS since I did not make any contributions. This means I have paid 3 times as much gas as I could have paid if I claimed only for a specific window.

## Claiming for a specific period
If you are sure in which period you made your contributions, claiming for a specific period is really easy. Most of the steps are taken from @sandwich's [The Complete Guide](https://steemit.com/eos/@sandwich/contributing-to-eos-token-sale-with-myetherwallet-and-contract-inner-workings) :

1. Go to https://www.myetherwallet.com/#contracts 
2. Under heading **Select Existing Contract** is a dropdown, select EOS Contribution
3. Click `Access`
4. Under the "Read / Write Contract" heading, in the dropdown select `claim`

5. Under **day** type in the period number in which you made your contribution. Example: for period #7 you would simply type `7`
6. Load your wallet
7. Click `Unlock` button
8. Click `Write` button
9. Set **Amount to send** to `0` and allow the wallet to suggest a **Gas Limit**. If it does not auto-populate, enter `90000` or more. If your TX fails, increase **Gas Limit**.
10. Click `Generate Transaction` button
11. Check the details of the transaction, and if you are confident with the details you have entered, click `Yes, I am sure! Make transaction.`
12. If all went well, a green bar will appear at the bottom of the page including a link to your transaction on the blockchain.

Below is screenshot of my claim for Period #3. It returns with a single line of 0 EOS Tokens.
