Online resources for visiting Ghana

A couple of excellent online forums to find out about travel in Ghana, or life in Ghana, are:

Internations.org

Internations works on trust and they verify your credentials before being allowed to access the site fully. You can meet plenty of expats and get up-to-date details about living in Ghana, particularly Accra. They have an active expat community that attends regular meet-ups too. A good way to meet people when you first arrive in Ghana.

"InterNations is a community of trust and confidence, present in 230 cities worldwide. Data security and privacy are of major importance. Therefore membership is invitation-only:
You need to be invited to become a member"

and Lonely Planet's "Thorntree" forum.
This is geared towards short-term travelers and is essentially a place to find the most difficult to get information that may not be available anywhere else online. Many current and former travelers lurk around the forums and are ready to offer advice and answer questions from fellow travelers. When visiting Italy I developed my entire itinerary around the feedback on the forums. It was brilliant. I've read loads relating to Ghana there and the advice is helpful and mostly accurate.
