GnuCash Ver.5 and up - copying settings, especially reports

To copy the settings, particularly the reports you have already made, to GnuCash Portable, the instructions on the page at https://portableapps.com/support/gnucash_portable#local_profile haven't been updated for a while, and no longer work.
The new directory for the reports file (saved-reports-2.8, saved-reports-2.8-backup) and the other settings files, is at:
[drive]:\PortableApps\GnuCashPortable\Data\GNCDataHome
Note that copying files to the directory that is listed on the support page (GnuCashPortable\Data\profile) does not seem to do anything.
If you copy your Windows desktop profile folder from C:\Documents and Settings\[user]\etc to that GnuCash folder before running a new install of the portable version, then it will pick up all your old reports, which can be a big time saver.

Does anyone know how to contact the editor of the support page so this can be fixed up to help new users?
