Does Mi Yodeya offer personal guidance in response to practical questions about Jewish law or attitudes, as a rabbi would?
It does not!
An early version of this site had the following important disclaimer at the top, in red:
Like Wikipedia, mi.yodeya makes no guarantee of validity, and does not offer professional (particularly rabbinic) advice. Treat mi.yodeya information like it came from a crowd of your friends.
And we mean it! On a website like this you can get some interesting information and discussion, but it won't be tailored to your specific situation, where you stand in Jewish observance, etc.
Therefore, the community has decided to include the following in the Help Center:
Like Wikipedia, this site makes no guarantee of validity, and does not offer professional (particularly rabbinic) advice. Treat information you find here as if it came from a crowd of your friends. (Source)
