Got seeds - now what do I do?

Family: Cactaceae (kak-TAY-see-ay) (Info)
Genus: Rhipsalidopsis (rip-sal-li-DOP-sis) (Info)
Species: gaertneri (gert-NER-ee) (Info)

Boy am I glad this forum exists! Never heard of Easter cactus described as an orchid cactus before. Another DG member directed me here.

Managed to collect about 50 seeds from 3 very ripe (but tiny) little fruit. Are there tricks I should know about trying to germinate from seed?

Thanks,
Seandor
