Mailing list link to sympa's web interface missing

On the Mailing list tab of pages (like https://www.ohwr.org/mailing_list/show?project_id=fmc-pci-carrier) is the text: "You may also use sympa's web interface for subscribing/unsubscribing. "
However, there is no link to this sympa's web page. I suppose it should point to http://lists.ohwr.org/sympa/info/fmc-pci-carrier.

Can you please add this link to those Mailing list tabs?
Thanks!
Erik
