Mail your rilfe to me and I'll let you know.  [;D]

Here's some I've been able to find:

This forums is about rifles in general, but it seems to have a lot of M1A fans there:

Try www.jouster.com for some good M14 gunsmithing tips.  Scroll down to CSP Lane Tips then once that opens scroll down a bunch more to the M14 Tips section.  www.jouster.com does have a M1Garand/M14 forum but it's 90% M1 Garand discussion.

The M1A/M14 board at www.gunandknife.com is very good.  One piece of advice though.  They are real touchy if you start talking cast vs forged M14 parts.  Oh man, it starts a family squabble something fierce.  

I like Gun&Knife, but some of the topics are way too specific.
You think Springfield would sponser some site.

There is a good FAQ on M14s, AR15s and M1s at [url]http://www.fulton-armory.com[/url]
