[MlMt] QUESTION: How to access beta builds

[Jenna Jonteaux]

As an introduction to the group as a new user,
this may be the most noob question anyone can ask.

Here goes:
How does one access beta builds, release candidates..whatever they are 
referred to?

I have followed instructions to tick under Preferences, Software 
Updates, watch for Beta Builds, but none have come my way as of yet. Is 
there another resource where I might directly download most current beta 
release?

Many thanks for direction in advance, and an additional heartfelt thanks 
for one of the greatest pieces of software ever…I am impressed daily 
with its ease of use, strength and development. I am now a ZERO INBOX 
devotee!
