            switch(char_name=input("Who are you?","Idenitity"))
                if(lentext(char_name)>11)

//                  if(html_encode(char_name))

do
  name = input()
while(name_is_invalid(name))

mob/proc/name_is_invalid(var/name)
  if(name.len > 11)
    src << "Too long"
    return 0
  if(html_encode(name) != name)
    src << "No HTML"
    return 0
  return 1
