This forum has the special ability to have a user mark a certain post within that thread as being the best answer. This will visually show to everyone that the thread has been answered and no longer needs further attention.
People who are looking to help others out can then quickly assess the thread list and see which threads still need answering. If someone has answered your question/situation, please mark that particular post as the best answer. There is a link at the top-right of each post to mark that post as the best answer.
If you need an answer to be unmarked, a moderator such as myself will need to go in and unmark it.
