Thats for the quick reply. I found that as well, but I do not have a clue how to use it. Any idea?
One reason why I did not pursue this method was because it appears to have one negative aspect. If I am reading it correctly, it appears to reduce the username after the user submits their name. This may just be me, but that does not seem as optimal as it telling the user that their name is too long.
For example, if I set the limit to 15, it sounds like this will reduce any name over 15 to 15 automatically. If a user were to enter "Mynameisbillybobjoe" wordpress would automatically crop it to "Mynameisbillybo", which could have a completely different meaning to the user.
Thanks in advance
