Paid or unpaid, there is a moral obligation to see your investors through with an undertaking such as this. Further, you have to be able to perform the tasks ask of others in case others don't perform. That is what I do.
I have no problem helping out. There are so many of us that invested in getting it started. I'm sure I can live without a few nights of TV to make it happen for everyone. However, that isn't my decision but I'm here if you need me.
