Yes, you do. If you'll check out the Progressing Hacks forum, you'll see a "Rules and Requirements" sticky thread, you should read that for all the info you need :)
Hi there, sorry for the late reply to your question!
I'm not entirely sure what you're saying, but if I understand correctly, then generally I guess it's okay to talk about the hack in the team thread to some extent- however, it's not acceptable to use the Team thread as a makeshift Hack thread; so while you can use the team thread to give people assignments and so on, you shouldn't really post updates on the hack- it should have its own thread in Progressing Hacks or the Hacks Showcase for that.
Hey Giradialkia. I wanted to know if it is against the rules to communicate about a hack with team members in a team discussions thread. I didn't see anything against it in the rules, but it says to contact a mod if uneasy about something, which I am. Thanks, I just don't want to go against the rules on something.
