READ HERE FIRST BEFORE POSTING - List of important/useful threads to read/use

To try to cut down on the huge amount of stickied threads throughout these forums we will create "READ HERE FIRST BEFORE POSTING" indexes which give a list of the most common/useful threads to post in on various subjects and importantly where to find them, ignoring these "READ HERE FIRST BEFORE POSTING" threads and going ahead and posting something which belongs elsewhere (as covered in the index) will not be appreciated and I'm sure our moderatorial response in return will also not be appreciated, anyways enough of that:
