Editing
Editing articles, that is to say add new articles and changing exiting ones, is easy in wiki's. First you need to register (don't forget to give working email) and you are set to start writing or iron typos out of old articles.
Usually there is already a existing template for what you are going to add that have a frame what all the article needs. E.g. Weapons, shields, armours, Items (things that are mainly used from inventory), projectiles, spells, skills, different quest types, societys and plants have all their own templates where you can copy the needed fields, paste it to the article and fill the fields. After looking trough preview the article looks ok, write what you did to summary field, hit save and you have contributed!
There are couple main guide lines about how to fill those fields. In 'description' field you should not inswert any additional rows, instead it should be all in one long row. The template automagicly word warps them. When adding anything else and you need a line break, hit the enter once more si that it has empty line betwean the two texts. This is a wiki 'languages' syntax to tell the wiki to that you want a real line break.
