Considering Google Checkout for our Zen Cart based site but...

[scatgc]

It seems that the Google Checkout Mod for Zen Cart has not been
updated for a while.

Is this because there are no problems whatsoever with it? i.e. 100%
bug-free and problem-free?

If not, what is the reason for what seems to be lack of support for
this Mod?

Also, the activity on this forum is extremely low, which to me
suggests that either very few people use Google Checkout on Zen Cart,
or... no problems at all?

Any recommendations or suggestions as to how to approach the Google
Checkout for Zen Cart challenge?

Thanks.
