Informative profile
If you also want to be taken seriously, do not be lazy and fill in your profile. Write something about your hobbies and other activities that keep you busy in life. Describe how you see your future. It would be good if you told others about what sort of people you are interested in.
Plan meeting in person
Chatting should not be your only option. You are looking for a relationship and sooner or later you’ll need to arrange a real life meeting. Sitting at home chatting for months is useless. You will never get to know anyone without meeting them face to face. Be brave and ask the person to go out with you.
