How many characters would you feel safe leaving for a First Name and Surname?
The users of the system are going to predominantly be from the UK (I mention this because some parts of the world seem to have peoples with very short or very long names in comparison!)
I will hopefully soon be getting an export of their current members list, if I do then I can take an average and stick on a couple of characters for good luck but I don't want to wait on it to start.
In the page I am creating space is at a real premium and I don't want to waste space on the name!
(Also, if someone with elevated permissions can think of better tags, please add them!)
