If you're interested in joining the iconpacks team, then please let us know. What does it involve? Simply, you'll be contributing to a project that is in the top 20 of mozdev's projects, and receives hundreds of visitors daily (see site stats). Things the project currently needs include: even more icon packs; a refined interface (if you want to have some fun with HTML/CSS/XML/PHP, please do!); and many more tweaks... it's completely up to you.
