What I would find most useful is a parameter format that has exactly the same effect as, say, https://mudcat.org/thread.cfm?threadid=120999#4223438, but without having to specify a threadid, so that it remains valid after the message has been moved. For example (i.e. not working yet!), https://mudcat.org/thread.cfm?messageid=4223438.

As a makeshift, "thread.cfm" may be reprogrammed to search for the message elsewhere if not found in the given thread - not really the best idea though.

I remember many music threads that have been reorganized by the elves, for good reasons. It would be even better if the "permalinks" remained valid.

Would someone please point me to a thread where all existing parameter syntaxes are listed and explained? The ones mentioned above I understood.
