The owner made some changes last week, the signature function no longer will post by default, you will have to check the 'include signature' box, or use the Quick Reply area at the bottom of each post. Also, there is now a 400 character limit to new or updated signatures as they are changed. So if your signature was more than 400 characters, it will not post until it has been edited down to fit the new requiremnt of 400 character. We are working on a work around for being able to get people signatures all in one place, so keep looking for news. It is also suggested that we only click the 'include signature' box the first time we post or reply in a thread, rather than include it each time we post.
