Not sure if this is the right area for this but anyway:
Plugin: Found Diamonds
Not exactly sure but I believe it shows if someone found an ore: mostly diamond
Would help with finding hackers
http://dev.bukkit.org/server-mods/founddiamonds/
Plugin: ModOnDuty
Makes it so you can put (if your a mod) that your on or off duty
Would help if you are a mod yourself
http://dev.bukkit.org/server-mods/modonduty/
Plugin: Stop talking auto ban
http://dev.bukkit.org/server-mods/stab/
Plugin: Hawkeye
http://dev.bukkit.org/server-mods/hawkeye/
Now I am not sure whether these are updated fully, or even if you already have these so just comment what you think.
I just wanted to take some time to look up different plugins to make the server better.
I like the ideas of these plugins and also Hawkeye is a good plugin to use but the server already has a greifing plugin installed. The modonduty plugin looks very cool. And i am aware that there is not yet a spamming plugin to be installed yet. but im sure there is always spamguard. these plugins look cool and fun and could be enjoyable for the server. And as for the found diamonds plugin it looks very good to use on players that look like they are using x-ray. I enjoy these plugins ;D
Thanks for the suggestions :D
I will probably add FD for at some stage, I've used it before and it's pretty good.
ModOnDuty I'll have to check out, but it seems pretty good.
STAB I won't use but I will install SpamGuard
LogBlock does what Hawkeye does xD
