As the Raspberry Pi is still relatively new, and it still has a way to go when it comes to distribution, I'm fairly certain that a lot of the site's visitors will still have not acquired one. Obviously questions about ordering and pre-ordering and the like will be on their minds. Will those types of questions be allowed?
I'd like to see them off-topic. Questions about ordering and shipping aren't really under the control of Raspberry Pi. They are under the various sellers, which we don't have any influence or information about.
Basically, we are here to answer questions about Raspberry Pi, not about Element 14 or Farnell.
No. Those sort of questions should probably go to the foundation's forum.
They should be closed with a pointer to an FAQ which has links to the web sites of suppliers.
I'd like to see them being considered on-topic, but they may need to be heavily edited into something useful.
Questions that will quickly be out of date or are too localised should still be closed though.
