So far Ive been imitating how the more seasoned game developers post DEV LOGS about their games. For example:
ATaciturnGamer's post in this forum called "[Devlog] Knight Terrors! "
- Showing screen shots and videos of progress
- Posting in depth explanation of what changed since the last time they posted, in a way that other game devs will understand quickly.
- Having timely replies to comments both on thier thread and on other peoples
It all looks organized and neat.
