This is very good idea. Everytime i also found difficulties to find new signature campaign beacause there are many other service providers like signature design and etc. So i think if the forum will make different child board for only signature campaign then it would be very great for us and we can easily find new campaigns.
I hope the forum will give attention on this topic and take forward actions.
In fact, there are very few signature campaign on the forum who pay with bitcoins. There are old threads on the forum, which publish all the changes in these campaigns:
