Are you able to contact another member privately without it being in relation to a question or answer?

I know this is not Facebook but are you able to contact someone personally without it being about a question or answer? I’ve not been ab;e to figure that out yet. I ask because Faye in my Fluther said it was nice to have a friend who was in a similar position to herself in terms of our lives and have things in common with eash other. That made me wonder if people do communicate on a one to one basis and build a friendship. If they do can you please tell me how that is done? Sorry if I seem a bit dim but I’m still a newbie. Thanks.
