Encouragement is the backbone of learner's we need massive support from the seniors to grow like others. remember that class one is the beginning of education.
Before account of two, one must be counted.
I agree that Newbies should be encouraged but what do you mean by massive support from the seniors? How can the seniors support the Newbies in posting or in educating them? It is the responsibility of the newbies to learn by themself. Even Seniors were once upon a time a Newbies. They have learned by themself, they have struggled to come to this level.
Good posts are anyways encouraged by the forum members by giving them merits even if it is posted by a Newbie or a Senior member. Merits are not given based on the rank he is holding, we give merits by looking at their posts or threads created.
