I just launched a bounty program for my ICO and I have different campaigns people can promote on EXCEPT signature campaign. I've taken a look at signature campaign, but not sure how people create such complex signatures which have images and clickable hyperlinks. Any thoughts on how that is done?
Since i'm not a signature creator. One thing about signature is you would use Bulletin Board Code/BBCode. There is a program you can use and that is BBCode. Signatures are made by using BBCode to create your signature's picture/design. Most signatures are created by using BBCode. You can learn on how to use BBCode by this thread
