Rob, I'm a software engineer, and 'user cp' means absolutely nothing to me, and I would suspect, nothing to most other people.
'my settings' or 'my pprune account' would be clearer.
I REALLY hope you take some of the following suggestions in the positive sense they are intended !!!!!!!!!!! I am not whingeing, HONEST !!!!!!!!!!
From the number of emails you get about lost passwords, perhaps it might be a good idea to update the text of some of the prompts and links so that they are more clearly understandable.
There are a few things about pprune, such as the very small link text, highlighted links being yellow/invisible, some unclear link text and some strange formatting (notably on the login page - where tab doesn't take you to password from username) that could benefit from a couple of hours tweaking.
Also, I have seen quite a few posts about the PM facility. This is essentially broken to a lot of people as it is not obvious at all, as to how to use it.
Good luck with the new server, and thanks for all the effort you guys put in.
