Man, we get this on a weekly basis, "I spent X amount of time creating a thread/post and when I went to post, I lost it all." That frickin hurts.
I know. To save yourselves unwarrented grief there are a couple of ways to avoid this that I know of, there may be more, I'm not a techie.
1- Use a document program(Word) to create large posts. That way they can't be lost if something goes wrong.
2- The easy way, ie: mine, copy your post before posting. If something goes wrong, like the name you chose for a thread has already been used, you
still have it saved.
An extra minutes effort can save you the loss of a half an hours work. And the subsequent frustration.
I hope this helps guys.
Happy posting.
