Can anyone recommend the file I need to hack in order to increase the username limit? I believe it is 25 characters and I need it increased.
I'm not at my workstation, so I can't search for you, but here is a technique I've used for tracking down code specifics inside a code base. SSH in to an EE app server and navigate to
system/expressionengine. If you can figure out a specific expression that is related to limiting user name length (such as
count($username) >) you can use
grep to search through text/PHP files for instances of that expression:
grep -nr . -e "count($username) >"
You probably have to escape the expression because it is a regex search. But that command should recursively search and return what file and line number the expression is found in.
