Well I suck at reading instructions :( Having just found this promotion I enthusiastically bought and staked 1000 Alive (from 0) before putting my son to bed and then came back and realised I was meant to screenshot before I did that.

Anyway if this screenshot showing my 1000HP stake and at the bottom in the history that I staked that amount 2 hours ago is sufficient to enter then great. If it's not no worries - but happy to have staked it anyway - it's a cool project!
