That's 'cause I borrowed an idea from self, and made a community for those posts. jlweight is currently set up primarily for me to keep track of my progress, so membership is going to be severely limited. Jen may or may not join if she's interested, and if I happen to have a bet going with you about weight loss you may find yourself with an invitation, but other than that, you're welcome to monitor the community without posting rights. Nothing personal.
If I accidentally slip up and forget to tell Semagic to post to the community instead of my regular journal, feel free to call me on it. How else will I learn?
