that is just silly though. You cannot prove that you have searched and found nothing, or that you haven't searched at all.
If someone shows up asking how to build a piston valve, or how a hybrid works, it's a pretty safe bet that they haven't searched. On the other hand, if they ask how to build an effective ETG, or how to find the sound speed of a certain fuel/oxidiser mix post-combustion (both topics which have been discussed here before), we don't tend to mind. Some things are simply so well advertised here that posting a thread inquiring about them clearly shows a total failure to search.
It's nice to ask a question and get a friendly response.
Which is what you'll get, after you've made some good posts and contributed to the community. The problem arises when new arrivals to the site create threads where they ask, with grammar and spelling on roughly a second grade level, a question to which the answer is given in very plain language in a thread
stickied directly above the one they just posted.
Now, on to the actual topic at hand...
Much as I hate to say it, I'm with Tech on this one. If you don't like the current conversation in the chat, you're free to leave. The chat is not, as I understand it, a free service provided by the senior members to answer questions along the lines of "how do i bild teh pisten valv?". It is a convenient place for informal conversation among the members, and the anonymity can be quite entertaining at times. If you can't take a bit of banter being directed your way occasionally (and especially if you're the type who appears in the chat asking for instructions on how to make a burst disk), perhaps you shouldn't be socializing with people. We have a tendency to make fun of each other, and that's not going to go away any time soon. And once again, if you're too tired to bother trying to figure out who SpudBlasters 12 through 19 are, you're free to go do something more productive
