newt Well! not spam exactly. I personally have used c2 for few years(early days) with my personal account with license and I have also made games with c2 collaborating with people from this community. So this is like a known community to me. All I am doing different is using our team's new ID for posting this announcement. And yes newt currently not with C2.
Anways, to promote the game campaign, I think we may have to spread the news, media, etc to more & more communities. As long as the announcements is properly done (once), I don't think it is called spamming.
Thanks for checking out "It's TIME" campaign page, I appreciate it.
