A membership level is a step on ranking system on Earn2Life.com. Levels can provide bonuses to a member. For example, receiving an extra percentage of an offer's payout, or receiving your earnings quicker.
To advance your membership level, simply use the Earn2Life HUD to complete Pay4Visit offers. When your account acquires enough completed offers, and is a certain number of days old, you will automatically advance in level when levels are recalculated (currently midnight GMT). You can see your current level by logging in to you E2L Dashboard. Also, clicking on your level will bring up the chart pictured here.
