Have you heard of Shidduch in a box? For those having a wedding soon, there is a kit you can get that includes info questionnaires for the single friends and relatives of the happy couple. They are distributed at the simcha, and the bride & groom take them home with them.
When things are a bit more settled for them, they break out the questionnaires, and start redting shidduchs among their friends and relations.
They say they are endorsed by Rabbi Menachem Nissel, Rabbi Boruch Smith, Rabbi Dovid Orlofsky, and Rabbi Yom Tov Glazer.

It’s actually a very good idea. Where better to find your mate? How better to spread the simcha?
