I think you will find that the forum is provided to allow users to exchange information and support each other. Xceed staff do post on here but it is not their main job - so the time it takes, or even no reply, depends on what else they are doing.
I don't work for Xceed, but over the 3 years that I have used the product/forum I have found that other users who have had a similar problem will respond to the posts (and Xceed staff many times). The cost of support gives you priority email support where you can eMail a problem and receive a prompt reply - I have found this also works well.
