In modding terms, "IT Skills" is an umbrella term which includes things as basic as actually knowing how to use the basic platforms/software involved and being able to type, use email, and so on, to more advanced skills like being able to read, understand and even repair (if not adding to) the coding (or programming) which drives the whole show, no matter if whatever it is that you are modding is hosted on AO3 or elsewhere. Even if you take your coding problem inquiry to an external Help Desk, unless it's a service-wide fault, the first thing they'll ask you is: "do you know what the problem with the coding might be?" If you have even a vague idea because you know part of it doesn't look right, it can lead to a fix in a few minutes, rather than a few days.
"IT Skills" also includes the vital ability to be able to fix any mistakes in tags and so on. A glaring example of an exchange mod being both an egotistical berk and someone with enough IT skills to cause a massive problem, but not enough IT skills to fix that problem, was when Jenn amended everyone's nominations in Marvel comics fandoms she had no understanding of, and then publicly whined that separating all the nominated fandoms and characters back into their proper format was "too hard", even though the original nominators had provided her with their original nominations.
Modding an exchange like Yuletide also includes running the associated, additional channels, including the mailing lists, Google/Yahoo Groups, DW/LJ/Tumblr, the new Discord server, the old chat, etc. So yes, you can have some modding team members who have the IT skills of someone who died in 1631 as long as you have others who can step in and fix any mistakes that happen. (Ideally, your mods lacking IT skills make up for it in other areas, such as publicity, handling participant queries with grace, patience and timeliness, etc.) Because those mistakes will inevitably happen, whether it's that your tagset has problems, there's a coding issue causing lags, or your whole database is hacked because of security oversight.
With an exchange the size of Yuletide, you need members of your modding team with fairly advanced IT skills, because problems will inevitably happen even if your actual modding team hasn't done anything to cause them.
