We appreciate that some threads are excessively long, generally because many questions are asked repetitively and are then merged into the appropriate existing thread each time (plus, of course, the inevitable tangents like this one). Merging is the best that we can do to keep the Site relatively uncluttered.
Reading through them at least (hopefully) imparts some general knowledge about the subject, which (hopefully) leads to more refined questions.
We certainly do not mind questions, but we do prefer that members do a little homework first.
Previous experience is seldom a bad thing, as long as one can adapt to the CF way of doing things and avoid getting stuck in old habits. Previous experience is also not required for most occupations.
Regardless of the percentage of women in any given occupation, one is still going to be working in a largely male environment, for whatever that's worth. I'm not sure why you are asking that question, though.
