The thing that annoys me the most is when people ask for information or tell the OP to do something that they have posted they have already done. It appears they read the first post and then reply without reading anything else. For example someone will be having RO unit problems and post about it. If they didn't post it in the OP, they will be asked their tap tds. They will respond with a number. Then they will get asked that same question 2 or 3 more times in the same thread by new respondents. It has to be really annoying to be asking for help and keep getting asked the same questions in your own thread. It is like calling the help desk and getting transferred to a new person that just asks the same questions.
