I agree with Teresa. I didn't have any problems when I registered just over a year ago, but I also own this house in my name, and have lived here for years and years - plus I still have a landline phone. So many people have cell phones, that not having a landline makes it more difficult to verify stuff I think.
To me, it is well worth the hassle of joining - but since I wasn't hassled, I can certainly understand your reluctance to put up with it. Keep looking at it, see what prices are going for, and then decide if this is something you wish to pursue. I too trust the LA sellers more than I would ever trust buying plants on Ebay. The added bonus is that through this forum, we buyers have identified in several threads the sellers we like to purchase from. ~Jan
