Draft tasks without implementation
These tasks as drafts, meaning they largely need more work to turn them into full tasks. Perhaps you can help by trying to implement them in Oforth (after all, one of the key requirements for a task being non-draft is multiple implementations, preferably in widely different languages) but be aware that this may be difficult because of lack of definition of the task itself.

Requiring Attention
Examples
These tasks have implementations in Oforth, but somebody, somewhere, decided that the example implementation was faulty or in some other way requiring attention. If you're familiar with the task and language, please consider reviewing/correcting the example and removing the notice.
No pages found.
Other pages
These are other pages related to Oforth which require attention; with your knowledge and assistance, we can improve the quality of the site's content.
No pages found.
Not Considered
These tasks are not generally counted toward "unimplemented", as somebody, somewhere, decided that Oforth was inappropriate for these tasks, or implementations of them would be unenlightening. Feel free to try your hand at them anyway.
End of List
Again, feel free to try your hand at any of the tasks listed on this page.
