A membership level is a step on ranking system on Earn2Life.com. Levels can confer bonuses to a member, for example, receiving an extra percentage of an offer's payout, or receiving your earnings quicker.

Advancing in Level

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).
