Thanks Daniel,
We have dealt with the 2nd and 4th issue - that should now be fine. The 5th we are looking into as you are quite correct; we just wanted it to get some people to review it even though we did not have 100% of the functions in yet.
With regard to the first point we will add some wording in to make this clearer and with regard to the third point we are trying to explain to our audience (a largely non-technical base we imagine) what all the buttons do.
Overall did you like the site? Any major features that you would like to see added? Thanks for your feedback - we have taken it all onboard.
