First, one can use the search function adequately if one uses the proper terms in their title. In other words, instead of using something completely unrecognizable and worthless like OA, use the words oxalic acid. That way, the search function would actually work in narrowing down the threads.

Second, if one cannot follow the first point, I have no sympathy for your plight and quite frankly you come off as a bit of a whiner.

Third, I agree with OFG. OA isn't fit to use on a Varsity. Personally, I like Evarorust.
