Well, hi. I'm sure some/most of this is in the pipeline, but I think for the sake of completion, I'll post this.

1. No formatting buttons/formatting information when making a New Topic.
2. No 'Post Advanced' or 'Full Editor' that allows for a separate window to post.
3. The post text box should be stretchable when making a New Topic, or if clicking a 'Post Advanced' button.
4. No Preview feature.
5. Saving a draft would be nice. It wasn't in the old forum, but it'll be nice to have one.
