I think it's not necessary anymore as everyone can be a contributor in the forum, regardless of the rank.
In this forum, there are people who ask and their are people who contribute through their answer, and that's just what we really need.

TBH IMO, some members are just ranking up for them to participate in a signature and to get a good rate, after they rank up, that's it, they stop contributing because they got their ultimate goal already. We just want to see members sharing like a free community that rank does not create a big difference to everyone. my 2 cents.
