So what is the target of this game? Endlessly repeating the same 20 mods over and over?
I'd think we need to try to force the next person to use the "in the same modpack-relation" option or come to the conclusion that even that won't do. In order to diverge from the more mainstream mods.
Also, the "don't name a mod twice on the same page-rule" would allow for you to react to a mod with the same mod, if only there's a page break between the two posts. I'd suggest changing this to "10 valid mod-shackle posts between" before reposting the same "shackle" would be valid.
Lastly, there's some mods that are spread over several jars (mekanism, project red) and some jars that technically contain several mods (Mfr, mumble link, ars magica). I'd suggest we consider these together as one mod.
There's of course some core mods and add-ons that are used together with one other mod always and exclusively (Player API, CodeChickenLib). I don't know how to deal with those.
I'm taking this game way too seriously, aren't I?
