Just for completeness I'll post some of the forums with the more interesting
questions and some of my responses. Notice that there is some copy-&-paste
done by me, which may at times give a boring repetition of texts.

Also, no one from Linn's or TOE's forum particpate as I know now, but there
are two PMs out from me, waiting for responses.

The links are to the first "PE question..." post:
