Hi, after posting a thread and then receiving several posts commenting not on the topic but instead on the posters (known as meta posting), I think it is always a good idea to have a metaTalk page.
see this for more details:
quote from above blog:
"Millard: Matt set up MetaTalk sometime like 8 months after he started [MetaFilter], right about the beginning of 2000, because people were talking about MetaFilter on the front page. It's natural enough. People would say, hey what's with this, hey look at the post, hey this guy's a jerk. So he started up MetaTalk and directed stuff that was metacommentary to that part of the site. You could delete something and say, hey take it over there. If people wanted to have an extended argument that was derailing a thread, they could do it there. "
