I'm curious myself. Usually when a thread of mine with 1000+ views and 100+ posts gets locked, I get a heads up k message or PM.
If there was something offensive or against the rules, I will edit it, or a mod can feel free to edit out the offense part.
Either way, it'd be nice if someone would let me know why (digger, I know that mods do not OWE me an explanation, and I am not demanding one, just simply stating it would be nice to know why it was locked, if for no other reason, that would potentially help whatever offense was committed to NOT be committed again?)
