Hi luise, welcome to MR!
Yes, we read them. I suspect several others will be along shortly to welcome you too.
It's great to have publishing industry insiders around! I don't feel competent to answer your technical questions, but we do have a lot serious e-geeks
around, so I'm sure you'll get all the information you want/need. You might consider re-posting in one of the more technical forums if you don't get much information here in "Introduce Yourself".
