As per Martin's post on M6 forum he will leave it up as an archive forum for now until he decides what to do with it. I suspect if the forum doesn't crash setup in a read only state then he will leave it as is. If the forum continues to crash on M6's server then we could try installing it on this server as an archive forum, however I fear the database may have too many problems with it to save it if it continues to crash on M6 setup as an archive.
