I find it sad that of all the posts, none of them sent the poor letter writer to any primary sources.
1. Moed Katan 26a
2. Rambam Hilchos Taaniyos 5:16
3. Shulchan Aruch OH:561
Now you can ask your posek
One post in particular had the mindlessness to give halachic advice which included such pearls as “I believe”, “I’m not sure”, “and “I think”. On a different topic he paskened from his “feelings”. To this person, if you are ignorant, don’t advertise it.
