We can modify the creation request of a new page and send more comments/sources to referee, and we can reply to questions of referee in a request.
But when a modification request is send (its status is “Pending”) we can not communicate with the referee (we can send personal messages, but they are not save in the history of the request) for send more sources (in my last request I forgot do it) o do any correction detected after send the request (this last one is related with other suggestion https://en.numista.com/forum/topic154899.html).
In addition, the referee must be notify about our message.
I think this solves another suggestion https://en.numista.com/forum/topic146910.html
