Introducing myself again - not able to post new topics

I am trying once again to post my introduction because I am not able post a new topic. How long does it typically take to become approved? If the forum is broken or not open to new members, would now be a good time to start a forum for a narrower segment of composite interests? Are there any other forums out there that are based in the United States? The reason I am asking is that products in Europe will cost substantially more to ship to the USA, but the forums that seem to cater to the entire world. often refer to sources that are not in the USA.
