I generally copy any text longer than a sentence or two before attempting to post or send. Or, if I know what I'm typing will be long, I type in a text file, save regularly, and then copy the text into the CathInfo box.
Also, sometimes it seems that something didn't work, but when I look, the post made it to the topic afterall.
Our internet connection here is actually pretty good, but it is still rural and can be tempermental at times.
