I Don't see anything that is helping with the alphabetic sorting for the letters() function.
I don;t use it @ the MyDownloads mudule, I use it @ the Xdir + the Myedito + Xdir hacked to a phonebook, If you want me to... I can send you the whole module to look @ ... It seems to come from the direction of -
$rankings[$e]['title']
I hoped to implement it @ the MyEdito - so it more or less "close" my requirements from a "homepages" module, so If you want to take a look at a hacked Xdirectory with the "letters()" you might find the problem ...

Mith, I would have ask you too, but I'm sure you're loaded with code to go over
Anyway, it might be a really small thing we missed here, and then it'll be easy to add to a lot of mudules, so it's worth the try.
