Some weeks ago Savannah.gnu.org decided to remove the full KLog project.
I lost some information like the mailing lists.
The main lost was not the archive, as the KLog mailing list was old but not very active but the trust I had in the savannah.gnu.org support to free software as it is not the case… anyway…
I have created a list on Groups.io for KLog.
You can find all the info here:
Mailing lists
Enjoy!
