Any other way to know when a campaign is closed apart for reading through the long list in there tread.
Sometimes its added in the title of the thread if its full ,but sometimes you need to read in the thread dont be lazy reading it will help you to know information about the campaign you want to join or maybe you can ask in the thread directly if there are available spot for you.
So many people don't have any idea about whether the campaign is running or not. Before asking any question manager will update everything whether the campaign is ended or not. That's why i suggest the people every week you have to follow the ANN otherwise you will be trouble.
