This isn't about me or my time - this is about getting the alpha board done. I find myself in the ungrateful situation where I have no choice but to consider it my job to say no to well meaning people whose agenda I ultimately share. Sorry - really. Let's get past this now and hope for a continuation after the alpha where we can make something even better together. /Fredrik
