Actually, it's under "Glow Engines, Gas Engines, Fuel & Mfg Support Forums" which makes sense. The other parts of RCU are great resources, where many more people contribute. The amount of expertise that we all have access to is truly staggering. If you set up the MyForums mode in your user profile you can pretty easily access the forums you might find useful, while hiding the others. The size of RCU is absolutely amazing. If a person asks their questions in the right places, they'll easily get several of the best available answers.

Even better than that are the search tools. Whenever I'm thinking of buying a product, I'll use the Google tools built into RCU to find as much information as I feel like digesting.
