Thanks to Allah I remembered the following Hadiths by the Prophet Mohammad peace and blessing of Allah be upon him, regarding this matter:
"Seek an excuse for your brother.”
"The believers seek to make excuses for others, whereas the hypocrites hope for the downfall of others".
“There is no one who loves to accept an excuse more than Allah”
Later, I received an email from Taslimah explaining why she didn’t respond (she’s blogged about it), and learnt about Tiananda's loss.
As for those who haven’t responded yet, well I will continue to make the funniest excuses I can think of. Like “the dog clicked delete”!
