The way the checker achieves its speed is by looking up all substrings in its dictionary rather than passing every single diciontionary word over all substrings (which could take hours). So, for example, in order to find a match on something like "lgsstm" ("lego system" minus vowels), it would either have to know exactly which letters you dropped (in which case the lookup would be speedy) or it would have to examine millions of permutations of each vowel in each position (in which case it would be excruciatingly slow) and it might even find whole bunches of unwanted matches -- for example "leagues steamy" matching "lgsstm" when all you meant was "lego system", or "mound mayor angie" or "money dime ring" matching "mndmrng" when all you meant was "mondaymorning". I don't mean to say it's not a good idea to check (I think it is a good idea, just as a diagnostic for people) -- I just don't know how to do it quickly and efficiently without some really big iron. --Todd

(...) You mean, change from checking !->i to checking both !->i and !->l ? (It does currently check !->i -- did that not work for you in some instance?) (...) Good idea! (...)
