If you are new to the forum and/or starting a new thread, consider -
Using The Forum Search Engine (UTFSE)
before you do. Lots of topics are routinely brought up time and time again by different people and often there is an existing thread about the same topic which may have lots of useful information that has already been provided which may be of use to you, it may already contain the information you need or if it doesn't you can still add your post to it and people will try and help you if they can.
If you start a new thread about something that has been discussed many times before and don't get a lot of responses, consider that it may be because existing members have already discussed the subject before many times.
