Which professions are there to be found on Fluther?

If you please, do you want to tell what profession you have?
Are you an ace in your field, or a rookie?
Do you find yourself answering questions about your profession, or do you keep from it (for whatever reason)?

I’m a woodworker, from the Netherlands.
I don’t know all the lingo in English, so it’s hard for me to answer questions on Fluther about it.
