Hi! Welcome to SG. I've been part of this community for some time so feel free to ask me anything.
Noteworthy, is that for anyone to know that you've asked them you have to either ask them in their blog or by sending them a private message. Why we can't just click a reply button in our own blog to continue conversation there, we have no idea. The only explanation we've gotten is "It's always been that way. Is it really a bad thing to go to the other person's blog and give them a comment too?" Which, admittedly the answer is no since you have their blog all laid out in front of you too so you can read that if you want and actually comment on it as well as reply to their comment they left in your blog. So we've just kindo accepted it and gone along with it.
