I think there might be a bug in the display of the list of episodes that have a particular tag. If I search on "pr", for instance, it shows me the first page of results, and also reveals that the whole list runs to five pages. But if I then click on the "2" to show me the second page, it always says:
"Addventure Server Is Busy
The BEA Addventure's server is experiencing a heavy load at the moment, so CGI programs have been temporarily disabled.
When the load average drops the CGI programs will become available again automatically."
Now if it had done this once, I could believe that - in the minute or so between showing me the first page and my asking for the second page - the server had become more busy, but it's done it every time in my three or four attempts. Also, if it knows that there are five pages worth of episodes, surely it already must have done the processor-intensive task of compiling the list, and just displaying the second page of that list should be trivial in comparison.
