Nick prefix change

[Kaszanka_1234]

I think it might be a good idea to change the nickname prefix from "Nick: " to something different (eg. "~" like it is by default) because a lot of people get confused and they think that the name of a person with changed nickname is in fact Nick.

I agree Nick is very confusing to some people and I think it would be better if it was more obvious as well.

+1, Although I suggest the star "*" symbol prefix.

That would be a large improvement
