I have noticed that, after creating a small web site on my Bullet M2 node, that after editing various files and deleting some, that the "free flash space" as reported on the status page of my node always decreases. Now it says 868K. How would I increase this,or do I need to completely reflash AREDN on the node (maybe the flash needs to be completely erased to get the space back)? In the future, I'd have to test my edits elsewhere (like on my PC) before loading it onto the node, to avoid wasting flash space.
