Some personal information
If there is
no response to your email for some time ..
Note:
Because of massive amounts of work pending, responses to any kind of
correspondence may be significantly delayed (actually so significantly that
I think this note is required - don't wonder or worry if it should take
months in some cases). Nevertheless, your input is appreciated.
Also, updates of these webpages are still in slow mode with a long queue of
stuff waiting to be worked in; sorry for any inconveniences this may cause.
