I just saw that there are two different ads for scifi.se at the Community Promotion Ads 2013 question. Does that mean it is ok to post more than one ad for a single project?
Yes. People are welcome to vote for both or neither. Only the ads the community approves will be put in rotation. However, you shouldn't post the same ad twice.
