Sometimes, when the server times out (due to delays in posting), you must login again, however not all times will it automatically post, while other times, it goes to a blank form.. and you've, effectively, lost what you had before... or reply on copy and paste.. to be sure..
Why does this happen? Can't the sever always post, regardless of timeout. (ie. if you do have to login again, it automatically keeps what you typed previously, login/ then auto posts)
