Here are some suggestions that might be considered during the site upgrade. All these suggestions are already implemented on other well-known sites, such as TenForums:
- Allow file uploads.
- Option to receive email notification of new posts in a subscribed thread.
- There should be a "Quote" button, next to the "Reply" button. The effect of the Quote button would be the same as for the Reply button, but the contents of the quoted post would be prepopulated in the Reply text box.
- Editing a post should not update the date. Reason: updating the date bumps a post - which the poster probably did not intend.
