Hi again!

thanks for your comments, makes me feel confident
I just went back to my frame after work this afternoon and I tried to see how much of the frame was moving by pushing on the queen posts again. It looked like the all frame is vibrating, even if my braces on first floor are pretty tight. So I tried to screw back some long 2x5" braces outside (like you can see on the first bent on the picture and bracing both sides it looks like the frame is stable then..

So my conclusion, reading in addition your comments, it will become stiffer with the sheeting and i guess i'm gonna make it technicaly more braced while I'll build up the walls. Roof will come along I guess. I keep you posted
