Hi, I've been following this project for quite some time and decided i should help out.(tried to join earlier but had some problems logging in)
I will Probably be doing more work on skyblivion as i have put countless hours into oblivion and know it far better than morrowind. (playing Morrowind now and enjoying greatly).
I have very little experience modding with the creation kit, but should have no problem learning to do basic tasks that need doing.
as i understand the best place to start would be helping with NPC conversion(fixing the current NPC's which are looking ridiculous atm sounds fairly easy, i can just use UESP to get them looking right).
i look forward to being part of this wonderful project.
edit: looking around it seems like a reasonable place to start would be tweaking current NPC's to look like they did in morrowind (some variation of course) as well as setting them to correct race etc.

I would highly recommend
I would highly recommend starting with Skywind, as Skyblivion doesn't really have any leadership at the moment. But hey, if you really wanna start with Skyblivion, I won't stop ya.
