Hi @Aldarc,
also welcome from my side of well!
As @Rayce_Kaiser wrote, there is an active D&D 5E community around (the V.A.L.U.E group), but beside this, there is an open D&D table game (which is more like old-school 70’s-80’s basic D&D / AD&D, before 3E),
we have some Call of Cthulu one-shots, in late June-July we shall play Star Trek (under pandemic we have planned a Cypher game, maybe it will happen somedays) and generally some one-shot games pop on the forum from time to time, so stay tuned!
