I'm considering starting a wiki (for an unpopular manga). I want to know how much (I need numbers) time I should expect to spend on this project. What are some tips? I'm considering writing maybe 20-30 pages offline first as well as drafting a rough sketch of how I want to organize everything before actually making the wiki. I have a preference to write by hand first. Also, how much technical know-how do I need? I've already checked out a library book to help me learn html, CSS and Javascript.
Should I just start small by expanding a free-range (no admin) wiki? I have one in mind. I've edited before just on a different account. I've only added readable content. I'm horrible with images.
What are your experiences?
