New protocol for this thread
* For each halacha posted, a source should be provided, even if that source is just the name of the rabbi you heard it from, or a link to a shiur.
* No commenting at all beyond that (besides if the OP of that halacha wants to correct something.)
* To comment on a halacha, post your comment in the halacha comments thread, and provide a link to your comment here in this thread.
