If you don't already have one, start a blog at a site like wordpress.com and create a post introducing yourself to the Mozilla community. If you already have a blog, feel free to use it!

For an example of a great introduction, check out Jessica Klein's post entitled Hello Mozillians.

When you're done, create a profile for yourself on mozillians.org, the Mozilla community directory. Be sure to mention your IRC nickname and your blog's URL in your bio, and add yourself to the P2PU group. This will make it easier for your peers to learn more about you and contact you if needed.

Feel free to post a link to your blog post here and in #newbies.
