Thanks again for the responses, much appreciated.
More D-P & chinny - Yes, I have thought about going to Africa. And I'm beginning to look at it more and more seriously at the moment as the chances of a job here in the UK are not looking too good, though not for the want of trying!! I'm thinking of maybe going down there to knock on a few doors when I have enough money to go there and spend a bit of time doing so. From the people I've spoken to about it, it seems this is the only way you're likely to get a job down there.
Daifly - Thanks for your advice. As you say, I don't want to annoy people, so it's a balancing act trying to decide how much to pester people before I become a pain.
drexel - I'm obviously in a position hours-wise that I hope others see things as you do and take a punt on a low hours pilot!! Fingers crossed.
Thanks again.
