in the forum you make this thread is very appropriate to make your signature campaign posts, but use the ability to analyze constructive things to discuss so as to provide useful discussion.
my suggestion you can post your signature campaign in bitcoin forum or altcoin forum. this is one of the best way to do your signature campaign. all of the user go to bitcointalk to have an idea what bitcoin or altcoin works, so posting in any forum will help you to do your work or rather increase you earnings. there are a lot ways to post your signature campaign but my suggestion is the best way you can have and i know some of other suggestion will be the same as mine.
