i hope the forums have a good search-function,
fastest way to search the forum is often using google with the site parameter: e.g. "serial 345600 site:arduino.cc"
Probably the biggest problem with the forum is that some very nice gems just fall off the map and end up 26 pages in, where no-one can remember exactly the title, or even which thread it was in ... was it Programming, Comms or Project Guidance?
And even Google searches (which are far preferable to the inbuilt search) aren't much use if you are trying to find the circuit diagram for a low-side MOSFET driver, unless you can happen to remember the file name.
