Hello, i do not want to create many topics (please don't ban, i'm giving this info maybe to improve?), but i want to ask:
1. how i can make input [type=email] with in form helper ? when i try to add to extra ['type' => 'email'], it's ignoring it
2. second thing when i changed password in this forum should not i get message - green alert 'successfully changed'?
3. this login modal looks in my monitor like that (1440x900) ^_^
