So it seems that Lewis Caroll wasn't quite good enugh: Wikia feels that the poem needed some substantial alterations. Nothing wrong with a few edits.Or a wholesale misappropriatio. But it would be better - as in honest, straightforward, taking responsibility and keeping with the avowed transparency of the site - to clearly show that the version in Wikia is in fact not what Mssr Carroll actually wrote.
I thought he did a pretty good job.
If you think it can be improved upon, God Bless. But don't try and pass it off as the original.
