I apologize for the disappearance of your two comments on my previous blog post, especially when they streamed through the email traffic and arrived in my e-box smoothly. I've given the system settings a check-up and found nothing out of order. As you said this i-engine is a pit. I've had similar problems with commenting on other's blog. Sometimes I managed to wiggle through by using a different email account which seems on friendlier terms to that particular "engine."
Before the problem goes away, feel free to email your comments with return address so that I could reply.
Thanks for corresponding.
And, Happy New Year!
