Welcome to the Geometric Algebra google group.
This group is moderated, but if you post something that is on topic, all future posts will be allowed without moderated.
Unlike stackexchange and physicsforums, the google forums software unfortunately has no integrated latex markup support. Given that, if you have a fully formed self contained question, you are probably best to ask on https://math.stackexchange.com
(which didn't exist when this group was created.)
