I've received many emails from bloggers who haven't been able to comment on my blog the past few days. I checked from my computer at school where we use Internet Explorer and have the same problem. But at home, where I use Google Chrome, it's not an issue. Shane from Roses, Lace and Brocante suggested I change my comment settings to pop-up window rather than embedded so I've done that even though I switched from the pop-up window last year because of problems.
Hope your day is a good one!
