@Rainer> Yes, sometimes discussions are going off-topic here. However, I'd think it would be preferrable if we called each other to order in such cases, rather than outright removing posts without comment. And if you think a post should be removed, please flag report it and have someone else decide and remove it – if it is indeed a violation of one of the Six Rules of Agoracom .
As you are well aware Rainer this is one of your rules and does not apply to this forum.
To avoid the unnecessary work load associated with managing violations pleased be guided by your judgement as to the appropriate actions required to maintain this forum for all readers who want good information in a timely manner when discussions are active to avoid bogging down the forum with noise.
