[@davetronred] Welcome to the guild, fellow Roll20 user! :sun

1) By private forum, there isn't truly a way for something to be private unless you create a private message thread, which allows up to 5 people to post in it. However, if you don't care for people following along and reading the RP, you can simply post a thread and mark it as full, which will show that the RP is not accepting players at the time.

2) Sadly, email notifications are not yet a thing. They used to be on the older version of the guild, but since the reboot, they have yet to be added.

3) Yes, you can embed rolls. All you need to do is copy the roll's url and link it with the following command: [noparse][url=Url Link Here]Roll number or whatever you want to type here[/url][/noparse]. Alternatively, you don't have to do the fancy url stuff and simply just copy and paste the link in your post, but I think it looks neater the other way.
