I tried multi in yesterday's Challenge puzzle and was a bit surprised that it didn't count.  Although it's primarily used as a prefix, there are plenty of other prefixes that count as words in Chi (e.g. intra, infra, demi).

Multi can also be a noun (a pattern of several colours or hues, usually in stripes according to dictionary.com).

So I'd like to suggest that it be added.

Since the beginning of this year, I've been keeping a tally of my rosettes (yes, I really am that obsessed with the game!)  I often wonder how my tally compares with other players.  Keeping an eye on the scoreboard gives you a broad idea of who's getting them and how often, but even so, it would be nice to know some actual numbers.  I wonder if it would be possible to include a cumulative rosette tally for each of the three versions of the game.  Are other people interested in rosette tallies or should I seek professional help for my obsession?   

I was somewhat surprised that these two words were classified as rare in the Challenge puzzle a couple of days back (the HISTAMINE game).  Both are pretty common, I'd have thought.

Yesterday's standard puzzle (SKEDADDLE) yielded more than 130 rosettes.  I can't recall seeing that many in a single game before.  Is it a record?  (I know Alan has provided stats on a previous occasion, but I can't find the thread).

I was also rather pleased that dalek was accepted as a rare word.    

One of Chi's quirks is that a number of terms which are prefixes or combining forms are accepted as words.  Infra, intra, nano, demi and hemi, for example, are all accepted as rare words, while others, like mega, are accepted as common.  Still others, like multi, aren't accepted at all.  Technically, I'd argue that none of these are words at all; they're parts of words (try using one of them in a sentence without attaching it to the front of another word).  Nonetheless, I've learned to look for them. 

And to make things even more interesting, there are words which are both prefixes and words in their own right, like semi and ultra (both accepted as common).

Although the pedant in me wants to eliminate non-words from the game, I've kind of got used to the fact that the Chi lexicon is quirky and that this part of its charm, and part of the challenge of playing.

I admit there's an element of sour grapes here, because tatters was the only common word I didn't get in yesterday's 10 letter puzzle, but isn't it the plural of tatter (a shred of fabric) or a form of the verb to tatter (to become ragged) and as such, not a valid word in Chi? 

Equally vexing is the fact that tatter (which I did get) was rare, yet tatters was common.   

Although I got glutes in yesterday's Challenge puzzle (having remembered it from the last time it raised its ugly head) I must renew my objection to its inclusion.  Every dictionary definition I've read lists it as the plural of glute (referring to the gluteus muscles).  Clearly it does not conform to the rules on plurals and should be expunged from the Chi lexicon.  Interestingly, the singular form, glute, was included as a rare word, while glutes was listed as common.  I find this difficult to understand.  I promise this is the last you'll hear from me on this subject!           

Yesterday's 10 letter puzzle included orated as a rare word.  It's not the first time it has come up and I've always been surprised that it isn't classified as common.  I'm pretty sure orate counts as common (though I might be wrong).  In any case, I'd suggest that orate, orated, orator and orating should all be common.
