A quick note here for the forum,is we don't always know what your reference is.
This is not the "direct voice of the corp",so correct answers may not await all questions.
There is no 24 hr "google" hanging around .
We are a bunch of cooks, around a few continents,sharing where/when we can.
Maybe, every several days.
We all try to help ,or steer folks to someone that can.Think of a local beer joint.It could be awhile before the cook with the "specific" info drops by.
Please be aware of what you ask,because the answer will reflect that.
Example could be: BUILDUP of most anything ash,grease,firepot,that could happen.Anyway,you get the idea that we are just like a guy you meet at the 7-11,except we have some of the same interests you do.
The more specific the question,the better chance that some cook will drift by with a thought-in a day,or two.
