Well, I wish I had known this a long time ago. I tried to reply to someone's question yesterday and could NOT get it to show up.
Comments are moderated, which means that I get an email to approve them before they are published. If they have any general interest, I publish them, and reply when appropriate. I usually answer two to four questions each day.
What I didn't learn until today is that the hosting site has a bunch of filters that flag stuff as spam for reasons that are not entirely clear to me. It's great that they stop me from having to deal with Viagra ads and cheap real estate deals. Unfortunately, I just learned that they are blocking a lot of significant questions that I would be happy to help with. I found this when the spam filter was blocking my own reply.
When I published my own to the blog, I published some more, but now I can't find them to answer them. If you sent a question recently, please feel free to re-send it.
SO, I apologize for the unanswered questions. I'll be checking the spam comments folder from now on.
