There was (and is) a special feature at the bookcrossers.de - page.
If there the BCID is typed in (anonymous) but no JE is entered within a certain time a JE-entry 'generated' which says this:
"Hinweis von BookCrossers.de:
Dieses Buch wurde gefunden, da die BCID über die Supportseite eingegeben wurde.
Leider hat der Finder sich nicht getraut ein Journal zu schreiben.
"notice from BookCrossers.de:
This book was found, because the BCID was entered at the support page.
Unfortunately the finder hasn't dared to write a journal entry.
You see such an entry here:http://www.bookcrossing.com/---/12753374http://www.bookcrossing.com/---/6681366/http://www.bookcrossing.com/---/11975574/
Before the great change of the Bookcrossing-page at 2010 this mssg was generated autmatically by Bookcrossers.de but since 2010 Wyando it entering those notices manually.
It would be really great if this feature could be adopted on the Bookcrossing-page.
It's quite encouraging to hear from a book at this way.
Why don't you introduce something like a crowd-founding for new features for BC?
I think, a lot of German bookcrossers, who know the feature from BookCrossers.de would be willing to donate towards this feature.
Maybe it would be possible to create a shop item/donation button at the shop to collect money for a special feature, e.g. with a bar-system which shows how many percent of the needed sum is already collected.
