I was backreading some topics in Marketplace and found out that signature campaign was not included in the first service of this website... What if Signature Campaign was never introduced... What else could be the Service we can apply for?
Forum is just a forum where you can discuss things related to the forum but since this forum become more popular because the inventor of the bitcoin made this forum, and many bitcoin users use this forum and day by day, and month by month, so someone make this forum as an advertisement platform for their service like gambling and exchanges thats why signature campaign was made. Even there's no signature campaign here this forum will still be popular and well known. As what I said forum is for discussions and some information, and marketplace board will be the place where you will sell and buy services so if you dont have any services to offer then you should find ways to make money.
