+1 on the search feature. Whatever your question is, it has been asked. Many times.
However, people have new experiences all the time, and collective wisdom evolves. So *after* you use the search feature, if there's any confusion, please feel free to ask. No harm in a good discussion, even one that's just a repeat from last week/month/year.
Besides, turnover is pretty high here. Check out some threads from a couple years back and chances are you won't recognize a single name. Sure, there are a few long-term addicts, but for the most part people come and go, and the knowledge doesn't always get directly passed on, so old discussions can be rehashed with new people.
I really enjoy finding posts from current "gurus" back when they were young and unlearned in the art of the planted tank, and consequently sounded like ...well, noobs. Fortunately, I've never been wrong. Ever.
