If you find security problems, email me directly (email@example.com) and don't post them on lj_dev ... that way I can fix them before they're exploited. However, hopefully nobody will find any security problems... I couldn't, nor could the dozen people that reviewed it, but maybe we weren't looking hard enough.
If you have questions on installation, post your question to lj_dev. Feature requests should go to the 'suggestions' journal. See the HACKING file in the LJ source release for how to submit patches.
It's a nice day out..... I'm getting out of the house.
