Bob, you should now be able to use that orange add media button above the edit screen to add pictures inline. Let me know if you still can’t. You can adjust the size displayed to pretty much anything you want after uploading by clicking on the picture and the pencil icon. For animated GIFS, that has to be set to full size, any other size you get a static jpg.
All the items in the editor should work also. I’m going to set the forum structure to match most of what we have at dagger bay next, then see about getting some smileys like we have over a dagger bay that can be put in the posts.
