Good luck, man.
You could probably edit your thread to make it look a bit better (get some graphics in, use some formatting, and so on)
But this is absolutely the right place to post a thread for your regiment.
Also, some regiments are using discord, some are using TS3. My regiment still uses TS3, as we're used to it and it fits our needs better than discord. But discord can be enough for a regiment, yeah.
