Mo' Creatures would be a good addition. I haven't checked the spreadsheet, so I don't know if it's on there yet...but yeah, I've actually been messing around with the Mindcrack modpack, removing some other things such as Thaumcraft, Thaumic Bees (because of the creator's issues with giving permissions), Xycraft, the Portal mod and testing it out in Single Player just to make sure that nothing breaks. I was also trying to remove the force field modulator stuff but I don't know if it's part of one of the bigger plugins like IC2. As well, I did want to remove ComputerCraft, but Forge Mod Loader has some issues with that and I can't even start Single Player without ComputerCraft. So I decided to keep it in. I'm basically testing it in Single Player mode because I don't want to commit any changes to the server until I make sure that what I've removed will not cause any world leaks errors on server startup.
As I've said before, my server is a dedicated Linux-based server, which is hosted by the fellow who created the site SteamIDFinder.com. I'm mainly just removing stuff that none of the 6 people (including me) who play on the server will ever use. My server is whitelisted, very small userbase, and I started it up after watching YouTuber "bdoubleo" do some Let's Play on Feed the Beast on the private Mindcrack server. I wanted to start my own Mindcrack server, and now that I have, I want to remove some of the "fluff" mods (fluff being a nickname I've given to the plugins I've removed).
But hey, whatever helps me make a private pack that will allow me to add Mo' Creatures to it and not have to get permissions from 50 people, basically. I'll check out the spreadsheet later today (as it's 4:01AM at the time that I wrote this post up), compare it to whatever mods I've not disabled, and see who I have to get permissions from. Hopefully I can get a private pack key, it would help the other 5 people who play on my server out a lot, so they don't have to ask me whether or not they have to edit their modpack and remove a mod.
Again, thanks for the info Watchful
