Well, you could KEEP the sid and have a sequence that links stories and
topics together. Then you'd have the nice SID thing alive still, and then
deal with the space issue.

Or you could maybe have two tables that assign a sequence to a SID (story and
topic) and then those sequences are added to another table that links
multiple stories and topics together.....

Just a thought
