Hey there awesome Wikia helpers. I am looking for some help over at the Vine Wikia. With no admin and no active users who know code, I am left updating a pretty technically iffy Wikia so I came over here for help. I do not know any of this stuff so please be kind. I do not know how and where to implement code and I also don't know how to write or read it so explain to me like I am a child. I need help for the following :

1) How to automatically calculate the age based on birthday. I am sure there is a way because updating ages every year is a chore.

2) How to add and make lines in the Info Box and let them show only when used. I found several guides for this but alas, I did not understand any of them. This is the Vine Wikia Infobox and that was indeed made by me but that was my limit...

3) How do I remove a category page?

I think that's about it so far. Would really appreciate help on all this. You will be rewarded cookies and self-fullfilment?
