(since i am still stuck somewhere in the middle of "Administrat= ion Cookbook" lol!) Well, people, speaking from the point of the occasional poster and frequent= lurker i can see that smth is going a little bit out of hand in the lists. I remember my own thread 1-2 weeks ago about NOT IN working much better in 8.3 than 9.0, how much i was trying to convince people that it was not =46reeBSD related, nor other setting related, trying to convince mladen that i was not cheating with the explain analyze i posted, trying to answer= politely to Tom who was asking me to post smth that i had already posted 4-5 times till the= n, and i can feel the agony of certain members here.=20 Before i moved the thread from -admin over to -performance i had certain is= sues at my home's FreeBSD mail server. Thank God, some reply i wrote one late night on -admin didn't make it to th= e list. Anyways, that's open source. Great products, access to source and knowledge= at a negligible cost come with a price. So here is my advice to people in similar situations (me mainly!) : take a = deep breath, dont hit the send button unless you are=20 100% certain you have smth new/positive to say, take some time to do more h= omework from your part, even try to read/hack the source, etc...
