Inyanei geirus - very interesting! Converting the gentile spouse of a Jew, when to reject a convert, does the convert have to believe in the י"ג עיקרים and other fascinating discussions.
Tefilah for a choleh. Why must we daven? מדין תפילה or maybe for other reasons. Is someone sinful if he refrains from davening for the choleh [yes!]. How does one properly fulfill the mitzva of bikkur cholim? Is it permitted to write a kvittel to a tzadik on Shabbos or for the tzadik to rite a קמיע? It is pikuach nefesh, after all...
Great material. TASTE AND SEE!
