I'll do my best to behave and not post too many stupid questions!
There is never a stupid question or one that is too simple. I don't think I have ever seen any abuse for posting even the most basic of questions. If you don't know then you don't know so ask.
What is possible however is posting a question in a stupid way cr0sh just about covered that. Also only reviling vital information once the posters question had been answered. Like Oh I forgot to say will this work under water.
Personally what I dislike is someone ignoring what I put and carrying on as if I had never posted anything. If you don't understand terms used in a reply then ask, there are a wide variety of skill here and to spell everything out would be patronising and time consuming, but if you ask I will. Also some people asking questions are quite arrogant about it, most people don't like that. Someone once wrote "I have no interest in using code tags just to make your forum look nice, I just want my problem solved", which shows a total lack of both understanding and common courtesy.
