Years ago these things ended up in flame wars. I think the moderators still hold on to that view. Although I haven't see such wars in years in the Morrowind mod section.
:shrug: This topic isn't that good idea. All the mod makers do great job keeping Morrowind up 'n running. But if I have to pick one favorite, it's probably GhanBuriGhan, who initiated the Morrowind Scripting for Dummies; and Yacoby by continuing it. That could be by far the greatest investment in Morrowind's mod community. Almost all of us started with alt-tabbing between MWSFD and TESCS..
