Some guidelines:
1. Free speech - you can say anything as long as it is relevant and presented in a calm and polite manner. Swearing, SHOUTING etc. make your post more likely to be removed.
2. No zero value posts or threads, like "SELL SELL SELL"
3. No pointless or uninteresting threads.
4. No referral code spam
5. No NSFW content
but what if our project is really promising?
The rules still apply whether your project is 'really promising' or not. What exactly are you not not ok with here? You want to be able to shout and swear about it or what?
