Of course we could work around that limitation, but for ease of use I suggest implementing one. Unless there is one already there and I missed it some how.
All very well but would it be UK or US English. This site seems to cater to both sides of the pond.
I quite often adjust my words to cater for US gamers. I often put middle to avoid centre / center.
Why not both? Or at least have the option to ignore and or add words to the dictionary. I am American and I usually spell words as if I was across the pond. Such as "armour". By default that should be ok or again at the very least I could make it a word.
