That is your forum.

In your control panel, click "visit forum" to go there and look at it.
In the "forum/blog" section of your control panel you can add new areas to your forum.

Perhaps a stupid question: I made both a blog and a forum. The blog shows up on the comic homepage but the forum does not. What can I do to make my forum visible and accessible? Is there something I did wrong or am missing?

Hmm, the original poster deleted his post -_-
I hate that.

Well, to make your forum show up on the home page feature, it's prolly best to make a custom template for it and make the link to it yourself. I don't know if the link automatically shows up with any of the pre-made DD home page templates
I know that it DOES show up in the DD pre-made comic page templates, at least in the black and white ones.

I can't even find my control panel, it isn't on my profile

nevermind, I found another way, just go to the bottom of the help! how do I...? list and you'll see a button that says create a new topic, it also shows up in every other section that isn't the main categories list
