craftbook for bukkit...is elevators, gates, retractable bridges, light switches, improvex redstone stuff
runecraft.. which adds lots of different things from portals to buffs etc
mobarena - arena type things where players team up and fight waves of mobs and get rewards at end
itemcraft is a platform to be able to install modloader mods ie mo creatures (which is excellent), flans planes etc but as tefal said, this one would need client side modding (i dont mind making a downloadable client if peeps want it)
i bought a multiplay server a couple of weeks ago and have been testing them out, learning permissons and all the backend stuff..they work fine alongside most mods,
list of mods im running at the mo is:
Autosave
Borderguard turbo
Command book/World edit/World guard (awesome admin tools)
Craftbook 3.0 aplha
Dungeoncrawl (dungeon generator which is hard lol)
H2SQL
Heroic death
lockette
logblock
magic carpet (though i am having permissions probs with this one)
MySql
Permissions
Runecraft
Remote bukkit
SQLite
think thats the same as most of our mods??
If any1 fancies coming on to have a look, let me know and ill add you to my whitelist (its only a small 8 slot server jobby so dont expect linktart quality heh, i just got it to learn really)
