You're already on it, silly. In fact I don't think you've ever seen it in its original incarnation; I posted my stories and chapters there and asked for critiques from the readers. One of the criteria for joining the filter is critiquing the work!
Of course, this failed miserably.
Now it's just the filter where I occasionally post about my writing and ask for critiquers, as you've seen and invariably responded to. And since you've declared I should just send you everything,
tigerphoenix asks by IM and wants everything anyway, and all other people are hit or miss anyway, there's really no purpose in maintaining it just as a list to seek critiques.
That being the case, everyone else might as well have the chance to get insight into my writing life anyway, I figure.
