Pete,
Welcome to the site and well done to your 18 years service but most of all good luck to you when you walk out them gates
I`m not sure how long this site has been running for,but there doesn`t appear to be too many users as of up till now
I come out late eighties myself and there probably wasn`t as much help then as there is now,so I just got on with things,but as I`ve mentioned in my post have hit a mid-life crisis and trying to find something to change my life
Anyway I don`t know about resettling abroad but I`m sure with your service record you should have no problems making the move 
I`m sure your resettlement officer can give you the information required,if not,I don`t know if this site has links for the British Legion and SSAFA but personally I`ve found them a great help with one or two problems and I`m sure they`ll endevour to help yourself
The British Legion and SSAFA do actually have their own sites,so you`ll find all the information you seek on them which also give you links to many military or ex military sites
Pete,all`s I can offer yourself is the best of luck and hope you make the right move

P.S...AP THE `AMMERS!!
