Don't give it up Roz, your grammar is way better than most Aussies that I know!Are you sure there aren't so many spelling/grammar mistakes? (except for the mentioned ones)
Recently one person said me my grammar is terrible... but I hope it was just because I was so tired then... in other case prob I'll give up it
If there was one tiny bit you might correct though, maybe in your photo credits where you say "I own work (rosa)", might sound better as "my own work (rosa)"
