You can make it.
So I still need 1 merit to become a Jr. member!

There are two ways:
1) Buying a Copper Membership, which is not too expensive.
As a developer of Bitcoin Stash project, I strongly suggest you to spend a little BTC to buy a Copper membership.
Here is link for your interest:
Paid memberships. Nearly 0.0021 BTC!
2) Building up a good project, then supporters/ investors of Bitcoin Stash will give you their sMerits later.
This way, will take a lot of time, and mainly depend upon the quality of your project.
