Should Merits and signature campaign be the only cheer to have interest and feel satisfied with the forum alone, I've seen many members not having enough Merits and have been active on the forum, while some have also been very active and nit interested in participating in a signatory campaign, i think what needed to first define is your purpose for coming, this will now determines what you are after and how you can get it fulfilled, so don't tell me those not in a signature campaign or not having Merits got their immune weak on the forum by being timid or got inferior, but i think everyone likes the way he has found himself here since each user determines his fate all by himself here on bitcointalk.
