This is a good initiative mate since the threads in the service board for the non-profit signature campaign will get buried by other threads and you will have to see the next page unless it is bump by a forum member just like what icopress did with peach bitcoin sig thread.
That's a good point, anyway, having a dedicated thread as some had said might be the best approach to this which could be bumped once in a while as we often see users do on some threads. Of course, these projects are worth advertising but the lack of incentive attached to it is the issue.
I resolved to that suggestion as best because after reading what everyone wrote on this thread, I discovered that almost all who supported it are in campaigns and I believe that they will also prefer to change to another paid campaign if anything happens to the current one rather than a free service.
For this, you will only be seeing support for these projects by lip and not by action. The only time you may see otherwise is when a concerned user is not yet favourable to joining a campaign.
