Willing to volunteer on English only Drupal 6 based website

Hi there,
I am getting back to Drupal after about 3 years. Starting with minor bug fixes here and there.
And since I have some amount of time at hand I am willing to volunteer into these:
Drupal 6 based website
English only would be better, I have no idea of the Internationalization or Localization modules
Existing or Fresh new project
Could include some custom module (code must go back into Drupal)
Could include new theme (again, it must go back to Drupal), but I do not graphics so that needs to be supplied.
Thanks.
