There's an online, internet service which connects those who are praying for wives, husbands, children-in-law and spouses for others. The entire Book of T'hillim, Psalms, all 150 chapters are divided among forty people in the same time zone. Everyone says their allotted Psalms and the names of all the single people in their group. It's done on Rosh Chodesh, the first day of the Jewish Month.
The organizer doesn't do it every month, though it has been done for the past few. In two weeks, on Rosh Chodesh Elul, we will again be saying Psalms for matchmaking, asking G-d to assist. Please join us.
