By the time you have proofread the final post, or think of something to add or change it has timed out.
An hour or two would be better!
I just had a rude comment about posting four posts in a row. This is why. By the time I went to edit it had timed out. Please increase the editing timeout.
Also, when inserting an image into a post, it doesn't display in the editor until the post has been submitted. Thats annoying as well.
