As of today, there remain a number of hyperlinks in the wikis that refer to sympa archives:

pcbe13089:wikis$ find -type f -name '*.md' -exec grep 'msg[0-9]*.html' -H {}  \;|wc
     47     271    6503

These need to be replaced by references to attached copies of the involved messages. Note that uploading (=attachment) is done per-project, and it is here where the biggest nuisance lies.
