#OpenBSD #development poll
Which of the following Twitch streams/VODs would you watch of me:

1. Would you watch a Twitch stream of me doing routine ports work?
2. Would you watch a stream of me doing virtual porting workshops?
3. Something else?
4. All of the above?

Trying to think of new ways to get people involved.

Happy Canada Day! :toot: πŸ‡¨πŸ‡¦
