We'd like to see more Level X users and our current selection criteria is a bit strict. We've removed the FAQ Requirement from leveling up so more users should be able to reach Level 3 without any issues.
First and foremost, you have to be a Level 3 user. Get Level 3 first.
Promote your services offsite. Forums, social media, etc. Every current Level X member already does this, many are avid affiliates (see exjordanary and sean101).
Create social pages/accounts for your account & services here. Examples include Facebook fan page, Tumblr, Google+, Pinterest, etc
