I just found out. Lindale is a city in Texas. When I entered the BD I never thought long about my username, and the first thing that popped into my mind--Ainulindale--was where I based my name on. It remains one of the most interesting pieces I've ever read.
Only, back then I wasn't sure how to spell
Ainulindale, and I thought it was too long. When I collected my wits I wanted to shift the name to
Diwata, the Philippine counterpart of "elf", or something else closer to home or would make more sense, but too late. Oh well. What's in a name anyway.
