Hello, Isabella. There is no specific introduction forum or category here.
However, there is a strict limitation on participation in the Forum:
It is intended for professionals in the electrical field, with an emphasis on licensed electricians.
With your unrelated profession, you are not allowed to request advice or answers about a DIY electrical project, nor to give advice or answers to others.
You do, as a member, have access to some of the search and post status functions in the Forum which do not work for guests and you may be able to ask theoretical questions about some code issue or electrical best practice as long as it does not involve you trying to do electrical work for which you are not qualified.
Forum members (professionals or not) are not allowed to give practical advice to non-professionals, in part because without a shared knowledge background there is too high a risk that the non-professional might leave out critical information and be unable to safely follow any advice given. (Not trying to answer a question when the poster may not know enough to properly pose the question.)
