Re: Username starts from uppercase letter
Oh, I misunderstood what you were looking for. Happens to me at 5am.
It’s still not a good idea to mod the bp core. You can still accomplish what you want with a filter. That way you don’t have to keep track of your mod and worrying about an svn update or moving from one release to the next.
You could use the same method outlined above but replace the strtolower() with lcfirst() to take it back to normal.
Up to you.
