Did you ask "I'm a new member. What should I do?" when you joined the forum? If you didn't, then it doesn't make any sense to ask this now. You have been posting useless things to reach 30 activities and become Jr. member, and probably because you have been visiting Bounties (Altcoins) sections and have noticed that there are some of them which accept Jr. members in signature campaigns as well. So that is exactly what you are going to do without any second thoughts, because if you were to care about the forum or the knowledge served in here, you wouldn't have been wandering in Off-topic section for all this time.

And, congratulations! You just successfully got one more post to get one more activity point towards your race of reaching 30 and then becoming a Jr. member. Keep going on this path and all you are gonna get is a negative trust for being a spammer.
