You can just post any words in this topic that you find are missing, or think that should be added to the spell checker dictionary. Also you can report any possible issues that you may run into with it.
On a side note it's always wise to check over your posts yourself, as the spell checker is not perfect and can miss certain kinds of typos. Also it will only correct incorrect words, and it will not check for grammar related corrections so you'll have to do that yourself.
