I think I will find it okay once I get used to it, I hope!
In the meantime the pages don't always seem to load properly, so it becomes hard to read. To add this comment took more than one attempt. At the first attempt the add comment produced a javascript problem (sorry it didn't give any codes etc).
Too much seems to need knowledge, a silly example being in this case to add a comment, I had to first 'show comments', not intuitive.
It does seem strange that ratings can only be +ve, why?
