Tip: When you go to make a post and it "burps"
 

It's happened a bunch of times to me so I'm sure it's happening to many. You type a post, then either go to post or preview it and B-U-R-P, either you get a message that tells you are "no longer logged in" or you get a blank white page.

Not to worry. Just hit the "Back" button on your browser and it will take you to your typed post that is still saved within your browser's cache. Then either resubmit your post or hit preview again. It will work (even if it takes a few tries), it's never failed for me yet.

Cheers.
