I got a couple of question!
Is it possible to change a forecast before the time runs out?
Is there a way to make 2 different forecasts on the same project (I'm not sure about the amount so I'd like to split my wings in 2 different forecasted amount)? Doing two account on Wings platform is the only way?
yes you can change your forecast as long as forecast is live.
no you can split your wings. right now you would have to split your wings to forecast on 2 different project, but in beta you will be able to forecast with all your wings on many projects.
