In addition, one can become involved in the Ubuntu community. There are multiple levels to become an Ubuntero. Each of these levels confers certain rights and responsibilities. The first level is the Ubuntero (Ubuntu Activists); it does not require testimonials, recommendation, nomination, etc. One simply needs to sign the Ubuntu Code of Conduct. The Ubuntu Code of Conduct can be signed using GPG.

Here are the instructions to use GPG for emails in Gmail and becoming an Ubuntero:

1. Start Firefox
2. Go to Launchpad.
3. Register for a Launchpad Account (Use your good Gmail account (it'll make your life easier later in a few steps)- and don't use an account you would normally use for spam or online registrations- Ubuntu won't send you spam).
4. Login
5. In the top right corner it should say Logged in as [someone]. Click the [someone].
6. On the Left Column under actions click Update OpenPGP keys.
7. Now minimize Firefox and go to console.
8. In console, type gpg --gen-key (Note: You may use any good password that you wish, that should be secure)
9. Type 1 for DSA and Elgamal (default)
10. Keysize, whatever you want (1024 is fine, though the higher your number, the longer it will take to generate and it will be more secure)
11. Type 0 for key does not expire (default)
12. Type y for yes
13. Type the same name you used for your Launchpad account under Real Name
14. Type the email address you registered Launchpad with No comment (press enter key)
15. Type O for okay
16. Key will now be generated. You may want to continue using your computer and do stuff, as this will be used by GPG for random information to create your key.
17. In console, type gpg --list-keys
18. Look for the line that says something like the below: pub 1024D/ 2007-04-11
19. The key ID will be some alphanumeric characters which you will use for the next steps.
20. In console, type gpg --send-key --keyserver keyserver.ubuntu.com
21. In console, type gpg --fingerprint
22. Look for the line that says something like the blow:
23. Key fingerprint =
24. Your fingerprint will be some alphanumeric characters which you will use for the next step.
25. Select your fingerprint, right-click, copy.
26. Go back to Firefox.
27. Paste your fingerprint in the filed that says Fingerprint:
28. Press the button Import Key
29. Now you will be emailed, but the text will be encrypted to so will need to use the Firefox extension for GPG in Gmail (now you see why I said Gmail before).
30. Go to http://firegpg.tuxfamily.org/stable/firegpg.xpi in Firefox. You may need to let firegpg.tuxfamily.org install software.
31. Click the button Install Now.
32. Restart Firefox.
33. Login into Gmail and open the email.
34. In the bottom right part of the email (to the right of Reply), click the Decrypt this Email link. You will need to enter the password you chose for GPG.
35. Click the button OK.
36. Voila.
37. Now go to the link in the email and activate the key.
38. Now go back to your Launchpad account.
39. Under the left column under actions click Code of Conduct.
40. Save the file on your desktop.
41. Read the file and if you agree with what it says then proceed.
42. In terminal, type cd Desktop.
43. In terminal, type gpg --clearsign UbuntuCodeofConduct-1.0.1.txt.
44. Open the created file in a text editor and copy and paste the entire contents into the box provided on the Launchpad Code of Conducts page in Firefox.
45. Click the submit button.

If all is successful, then you are now an Ubuntero (Ubuntu Activist).
