I registered and it seem OK. How about a small giveaway within the forum? At least 5k - 10k satoshi just to check your site and provability. And when you're going to add your referral program?
I don't think that will be a good idea rather it will create a spam burst giveaway! Referral idea seems good and it's very common. Right now I see Coindragon is doing a signature campaign, they did the best decision to promote the platform widely!
Just be careful with giveaways if they are altcoins. It is illegal in this forum to do that as a few people innocently found out. You can actually give it away in bitcoin though, and I would also agree, spam burst is not sustainable. Keep it simple, sustainable campaign with good referral.
