Add some hints for "Restrict Possible Usernames" challenge

Is it appropriate to suggest hints that could be added to lesson hint/solution pages on the forum? If so, is this the correct place?

For example here

there are only solutions. I would suggest some hints:

  • You will need to use the | character to create two complete alternative matches
  • Both matches will need to start with ^ and end with $
  • you will need to use both the + and * in your solution

The forum is such a great resource. It would be great if there were hints for all more complicated lessons. This particular lesson is really difficult if you don’t think to use the | character.
