We're supposed to be providing research, but sometimes the points within a post are so obvious that research is unnecessary.
Given that ELL places less emphasis on research compared to ELU, I think that ELL may be a more convenient place for the OP to start to familiarise with SE English language sites.
A mod from ELL complained about my suggestion for no clear reason, and finally my post was deleted.
My suggestion is based on my personal experience, and the issue of research on ELL is real and consistent as far as I am concerned. This difference in emphasis on research is probably due to the different targets that the two sites have, but why was my suggestion rejected?
Does it mean that we are "kindly" invited to avoid suggesting ELL to new users from now on?
