I am very sorry, I have no rabbi. Askmoses.com was a very helpful source until recently. I have a lot of work, and I do not know what I can do on the Intermediate Days.
1) Typing for my parent’s work
2) Calculation for my parent’s work (nothing on paper)
3) Typing and calculation for my unpaid internship
I used to have friends who used AskMoses. They got some answers that I later learned were very, very wrong. I can’t say anything about their current Rabbis but last I checked they are not trustworthy.
There are many people who actually work on Chol Hamoed. They physically go into the office like on a regular day. I think it used to be more common years ago than it is nowadays.
