Hello Gheath,
in case no one is replying here on the platform, you can go to this table tennis club in Rheydt-Mönchengladbach to make new friends:
****://***.djk-rheydt.de/tischtennis/hobbygruppe/
they have a hobby-group that meets every monday at 19:30 at Turnhalle Waisenhausstraße, the entrance is at Stresemannstraße 70. That seems to be a nice event to meet new people and play table tennis without the need to register or becoming a member.
best regards
Thorgen
