Has my contribution arrived, and will it be accepted?

These two are the most pressing questions being raised in a number of emails over the past days - as said in an email, please be patient over the next days, as we need to assess each contribution and pass it on to the right peer reviewers. At this stage we'll get back to you and also let you know that the contribution has arrived, but it would slow down the process immensely, if, in addition, we acknowledged the incoming emails. But we are getting there in due course,
and thanks for all your kind support,
yours Markus
