Hi, in which channel should I post about a usecase and clarify my doubts about it
Can you explain that a little bit more? At the moment it looks like your request is better addressed in IOTA Discord.
This Forum is for research and governance discussions.
If your use-case question is research related you could post it in #research general channel.
Or you head over to our Discord, where you may get a quicker answer https://discord.iota.org
