I'm glad you're excited to share your project! Here's how you can do that without spamming the forum:
1. Choose a single thread to post all your progress on this project. This thread would work perfectly for that! Although you'd think posting many topics would increase visibility, it actually bothers people and reduces interactivity.
2. Edit your first post with a simple explanation of what your goals are for this project (you can edit the title too). Your goals are obvious to you, but we're not in your head so we don't really understand what you're trying to do.
3. Post the download link in this thread once your project is accepted to the archives so people know exactly where to download it:
https://www.cemetech.net/downloads/files/2808/x3728
4: Post screenshots by uploading them to a website like imgur and sharing the links here. People really like seeing your features working.
5. Try to post only one big progress update a day per project. If you post only when you're answering questions, when you've made meaningful progress, or when you need help, you'll keep the thread cleaner and it won't bother the mods.
