Thanks for sorting it out, Leah - I was worried that everything would be lost too.
I googled Sniper_Sa so many times and couldn't figure it out.
I did this too, although I only googled it twice before I gave up

. I guessed that something odd must have happened (i.e. a hacker) because I recognised/understood some of the weird red and black writing as UNIX/LINUX terminal code

.
Quick question: now when I preview a reply before posting it, it shows as a different colour than before (a grey preview background rather than white) - is this just a new colour format, or is something wrong with it because of the corruption yesterday (I'm in the US, so it was last night/this morning for me)?
