So this may be something alot of users of the forums may already know but I thought I'd post about it all the same. Sometimes when you type a reply in the forum and hit "submit", for whatever reason the post disappears and you have to retype it all. Can be frustrating if it was a lengthy response. I use Microsoft Internet Explorer and discovered early on that if this happens, I can click on the back arrow to previous page and recover my post. 9 times out of 10 it reloads in the post editor box with the text. Usually then I take advantage and highlight and copy it so as not to lose it again. You can try resubmit there but sometime you then end up with double post. I normally go back to forum, reopen topic and paste reply and submit.
It's been a handy thing to be able to do. I'm also getting into habit of copying a reply before submitting just in case - particularly if it's a lengthy one. Hope this makes sense and helps someone down the track.
