Hi and welcome to the Forum.
To answer your questions. At the top of this webpage is a link to our Discover section, if you select that, you'll get a drop-down menu from which you can access our Iceland Guide; please read that and follow any links it may provide; this will probably answer most of your general questions.
New Topics - to be honest, Iceland is a small country and topics will reflect the amount of interest potential ex-pats have in going there. Most ex-pats are looking for a better life, that generally equates to safety, work and the ability to communicate. I've only been there once and that was just passing through; my opinion (based on that) is probably not worth much to someone planning to go and live there.
Why don't you tell us what attracts you there, then once you have read our guide, if you have any further specific questions, come back to us?
Hope this helps.
