Comment submitted with empty message

[atzorvas]

seeing this post, the user has an empty message attribute.

To confirm this, I've replied with an empty comment as well (many whitespaces) - It worked

so before submitting, the string checked must be trimmed to remove whitespaces,
so " " will become ""

jquery has .trim for strings, and there is also https://github.com/epeli/underscore.string

@Elfoslav
this is not yet fixed, all forms asking input such as: bug report in lesson, asking help in assignment, private messages

ensure also that no other similar place has the same issue
