I am a newbie here and recently met a guy that told me he became a Jr member in less than 24hrs of joining the forum, is this possible?
No it's not possible. May be some one give you wrong info. There is time frame for increase activity. For every two week your activity will 14 if you continue make post. So for Jr. Members rank you need 30 activity. Almost over four week need. There is no any shirt cut.
