Make sure you have the beta wallet running which has the walking stick image on the pump page.
Look at the 'Next Pump' part of the wallet. Click on 'Find Address' and select your address with the largest coin balance. The 'Address' field and the 'Starting Balance' field auto populate now.
To get the Stealth Address click on 'Set' and a box pops up where you can select a stealth address if you already have one, or you can 'Create a New Address' and be sure to check the box that creates a stealth address. The 'Stealth Address' field will auto populate.
Click on 'Join Pump (Send)' and pay your 1 SNRG. That's it but was going off memory so if anything is wrong please point it out so I don't lead anyone astray.
Thank you sir!
