After a long time, i have worked again on this hack, and made some big changes.
now you can archivate all closed thread on your board (just a small change)
i have written a completly new makearchivroutine.
i think its better than the old one, bcause the colors are no longer hardcoded, so you can use different styles.
the new routine allows me to write a function, which will redo an archiv to a thread when you want to do so (in the next release or one later)
the old routine ist inside the showarchiv, so you can view your made archives.
in the next version i will release a converter (if this is possible

)
i have bit problem with the templates when you view an archive. Nothing serious, but when someone see what i made wrong (colums of author an real poster colum doesnt match), tell me.
please read the installation file carefully when you update your version, because ther are changes to the DB this time!
and
DON'T DELETE YOUR ARCHIVPAGES TABLE WHEN YOU HAVE ALREADY MADE ARCHIVS WHERE THE ORIGINAL THREAD HAS BEEN DELETED!!!!!!!
Hope you'll enjoy the new version.
The release is not too far away now

So if you find bugs, tell me please
PS. @Oro: If you want to use the hack on your local PC, you have to install zlib right. i have had the same problem lasttime, cause i have installed php 4.2.0 but not the zlib

if you want to check it without the zlib, just uncomment the function decleration gzdeflate in makearchiv.php and gzinflate in showarchiv.php
threads wont be compressed then, but you'll see how it works

i have testet it so myself
