There is nothing as good as been rewarded for active participation and meaning contribution to the forum. However, newbie who may not be considered a newbie after ranking up tends to go astray.
After ranking up to member rank, the desire to engage in signature begin to grow after discovering or having known how signature works. Hey this is not to scare you away from signature but I do really think, the quest to meet up with numbers of post tends to lead many to low quality posting
Don't assume to have known much just because you have rank up, but exercise patience to learn well and be more useful to the forum, this will also help you have more quality post than chasing cloud.
This is not a rule but a timely advice to newbie who wants to keep their posting reputation in good standard.
One meaningful post is better than 15 to 20 post that are low in quality just to fulfill signature requirements.
It is even rare to see signature campaigns that recruit member ranks and below so if a newbie is rushing to join signature, as long as the forum rules are not broken, I don't see any problem with that as it is up to the manager of the campaigns to select who they consider ideal for the campaign they manage. It is not bad to aspire to earn extra income from the forum as most of you make it look, it could just be a motivation for newbies to engage actively in discussions across the forum. What will become bad is spamming and breaking the forum rules in effort to appear intelligent or smart, something I noctice that is common among newbies.
Well I think you are right because as long as this Bitcointalk forum is concerned is very hard for you to see a signature campaign that is accepting member rank. Though sometimes I used to wonder why most newbie are always inquisitive to join signature campaign although we know that everybody need fund to take do one or two but is actually good for us to gether the knowledge first so that it'll enable us contribute meaningful in the forum and rank up to full member before thinking about signature campaign because even though if you don't learn how to make a meaningful post you are still going to find it difficult when you join campaign.
