bank account login permits dot, but wallet account login does not
When I created my bank account, there was the classic back and forth of trying short names until finding something not already taken - for me it was "jonas" -> "js" -> jonas.s" -> "jonas.sj".
Them after succesfull creation of bank account, I was prompted to create a FairCoin wallet as awell, but to my surprise I was then refused the reuse of login: Apparently wallet does not accept dot in login.
For UX sake, I propose to limit characters permitted in bank account and wallet logins to a common set of constraints.
