Behaaloscha Bulletin in PDF Format

If you followed the priority order in pesukei d’zimrah in order to daven shemonah esrei with the minyan, and it is now before you’ve said yishtabach, and you now see you have more time, you may go back and say additional sections, even though they are now being said out of order.

If you go into a Shul to speak to someone (something muttar to speak in a shul, obviously), or to call someone out , or to meet someone, you must learn something first in the Shul, or say at least a possuk, or a Halachah, or a Mishnah, and then do so; just sitting down for a few seconds is only an option if you are unable to do any of the above.
