>1) Is there a way to see a collapsed tree of the message tree in Fox, rather than having to scroll through all the messages.
Not on the Web, unless using an ActiveX. However, you have that in the Navigator which is presently in Alpha 5.
>2) Have you ever thought of adding a SQL Server thread?
Yes, that category is already part of the available categories. We had a forum for C/S before but it was better to add C/S to be a category for each forum.
