questions? Ask away! There are many divers on these boards, so anything you need to know should be able to answer... or use the search function i nthe bar at the top of the page... most subjects have been covered at one time or other... but that doesn't mean you can't ask again!
Welcome old bean, it would appear from my time, don't ask about agencies (as mentioned) or DIR, sooooooo many arguments (mostly funny from an outsider view). Saying that, there is a lot to be gleaned from many, been diving myself for 5ish years and am still happily learning.
Drink long from the cup if you wish to learn and you shall reap the benefits, and more importantly, meet a load of people with the same interests that you can meet up with and have a good time, long live socialising!!
