I posted a message to WO staff on a message site and didn't get a reply, why not?
Do not post a message that requires customer support to the WO Yahoo Group, or to any of the various forums or other sites and expect a quick reply, that's not what these groups or forums are for. In fact, most manufacturers will not post at all on these types of public forums. Those forums are open message forums that some of the WO staff visit from time to time, and are designed for users to share ideas and experiences with other users, and are NOT meant for WO to reply to support questions. As such, they are mostly uncensored, and while someone from WO may answer questions from time to time are probably the not a good way to contact William, or any of the WO staff if you have an issue that needs resolving. Often the staff at WO will want to solve your problem in the best way possible, and its not unheard of for them to offer specials or deals to solve problems for people, because they are so customer service oriented. Those types of messages are private discussions between WO and the affected party, and are not suitable for open forums. So the best way is to use one of the corporate email addresses listed on their web site at: http://www.williamoptics.com/support/
