Have installed K2 and had a play around with it and it is a fantastic component with amazing potential. There are a couple of questions I have relating to extra fields.

Is it possible to create validation rules so if we allow frontend editing we can be sure we are saving valid data? It would be great if there were basic rules you could apply to say a text field - such as (not empty)(A-Z)(1-9)(valid email)

Also with the text area field - is it possible to make this a HTML editor as opposed to a standard text field? Or should that be created as a separate field plugin?

Thanks!
