i think that i devised a strategy that will allow a happy medium. i can set people up as blog authors. blog authors' comments do not require moderation. then i can turn on comment moderation on at 100% of the time. that will allow the anonymous tips, threats and insults to get through and i can filter the noise.
let me know what you think of this. all you have to do is send me an email, i will send you an invitation, you click accept. you also have the option to accept with another account. make sure your profiles are turned to private.
