Yeah, I should have known better. The last 48 hours have been hit or miss...which seems to be "normal" now for this site.
You'll have spurts of good response, no problems posting, editing, etc. and then you will hit a wall where you basically have to wait. Sometimes these are long enough I go refill my coffee cup, or start my other browser up and look at other gun forums I'm on, see where my orders are in the pipeline, that sort of thing.
I haven't seen the Network Protocol Error very often, the site just stops responding, basically.
