I've found 3.3-dev in under he CVS snapshot on phorum.org - and it looks good :-)

I've switched on 'float to top' but it only works with new posts - the rest of the posts have a latest reply date of 1970 - looking at the tables in mysql it's not obvious how the thing works.

any thoughts?

fixed the reply date with the following sql call on each of the phorum tables

UPDATE tablename SET modifystamp=UNIX_TIMESTAMP(datestamp);

but it doesn't list the number of replies :-( in 'float to top' mode

so close yet so far....
