The views and opinions expressed in these forums do not necessarily reflect the stated opinions of the LGC; unless, of course, enough evidence is provided to cause the members of LGC to come to a conclusion that said views and opinions expressed on these forums are more reasonable and enlightened than the stated opinions of the LGC. A committee will be formed to determine if the new views and opinions will be incorporated into or replace the stated opinions of the LGC. At which time, if the majority of the committee agrees, changes to views and opinions will be presented for vote, and the results posted.
The concise method of "The posts on this public forum do not necessarily represent the LGC" may work, but doesn't capture the true liberal spirit of long winded analysis.
Or you could use the common method of other forums; "I'm right, you're wrong, apply banhammer".
