I have almost zero skills when it comes to modding. Most of my info is second or even third hand info. I do however have a pretty good understanding of resolving various problems that can occur with members installing mods, conflict resolutions and guidance, as well as pretty good (at least in my opinion) with working with alpha and pre-release or private mod testing. I have done so extensively in the past mostly because of my general understanding of how the various games work and what to do to resolve conflicts and get it as close to possible to if it is the mod being tested is the cause or not of the issue.
I have tried and played around with the GECK etc and changed some eyes and hairs on NPCs and such, even tried to place in an armor but other than a "certain tutorial with armor" haven't been successful doing it on my own. I do need to gain more experience but in all fairness I don't even have modded games installed currently.
All one has to do is attempt to start to mod to realize the complexity of the task to be appreciative of the shear work that goes into the mods we enjoy today. Those that currently don't appreciate the mods they use need to try to create something like it, then they will
