So I just found out that this forum software has a separate tag called iurl, which opens links in the same window. We should be using this for all the CYOA threads.
Which also means I'd like help updating all the damn things that we've currently got to iurl tags - if anyone has a moment to do some, please do, and then post here to say what you've got done.
I've done all the Adonibal threads, so far.
UPDATE: And the Beesnot threads - still the Khan and Angus to go
