Hello Dear friend, the first order of business on steemit is for you to get verified as a newbie, make an introduction about yourself, including your picture and it should comply with the date, then afterward you verify achievements 1 - 6 in the newcomers' community.

The #club5050 tag implies your withdrawal from the steemit platform, club5050 means equivalent cashout and power up, while club75 means more power up than cashout, and club100 means total power up for three months, I hope this solves some of your questions, Goodluck.
