I am trying to make a pattern match a username that has the following rules:
- No more than 15 characters
- Must have a full stop in between two strings
- Digits can only be at the end of the string
- Only 2 digits allowed
Example Fails
- .asdfa
- dadad.
- 1apple.pear
- apple.pear123
Example Success
- apple.pear
- ben.peach12
