Hi Mancklin. Currently our list doesn't have snitty, so it's no surprise that it's also ignorant of snittier and snittiest. And I couldn't find an entry for snitty in any of the online dictionaries, but it is listed in the two-volume Shorter Oxford that sits on my shelf above the stereo (let's hear it for big slabs of paper!) So, I think all three of those words should be allowed.
As for soba, it was suggested in this forum in April by Bobbi, and I agreed that it should be allowed. Somehow it got overlooked. (I'll resist the temptation to mention that the "New Words Added" topic in which the suggestion was made and accepted contains 32 other posts, most of which have nothing to do with new words.) (Whoops! Looks like I mentioned it anyway. Sorry.)
So I will try to remember to add soba to the list. (Udon is already in the list.)
