Yes I find it difficult for 3 days now to find another signature campaign to participate into. I am a full memebr and I do have good activity, however there were not new signature campaigns for the last days. May be there was one ot two new signature campaigns but they were full in some hours (when I was sleepping). thus your ideea is very good, to reduce a little the price to have some new good signature campaigns here.
I agree with you, I also noticed that new signature campaigns becomes rare nowadays. It's almost 2 weeks from now since I joined a campaign and it alarms me a little bit because the competition becomes stronger due to the increasing number of accounts without wearing signatures. I think I should watch this forum more frequently from now on in order to be updated.
