How do I make a page

how am i supposed to contribute if most stuff is already been added also i dont know where to get templates for when new stuff comes in such as pets and items

Oh, right. The wiki is 100% complete. I forgot about that.

I also dont know everything way too many items to keep track of let alone acquire i only have about 20 pets so i cant check to see if teh info on them is correct on ones i odnt have and im fairly sure for ones i do have it is correct so no point editing the info there

You can start by putting Talent EXP into skills xD

One of the easiest things you can do to contribute is get repair cost for items. Category:NeedRepair lists all the items that still need their repair costs filled out.

tell me how to damage my cupid wings and ill go looking for NPCs while 100% repair event is going on

You wear them until they lose a durability? Are we still playing Mabinogi?

wearing them could take forever is faster way that would gauarantee a damage in a maximum of 3 minutes ?

getting hit...

Wear only your cupid wings and go use Enthralling performance in Alby to make a bunch of weak monsters aggro you for a bit.

Why do you want to break it and waste money?

You can't repair full dura items.

sitting on 12,200,000 gold its not like it will matter unless it 1,000,000 gold per one point of repair

You can even do small contributions Splat. I often make edits to things that most regular Wiki users don't even care about, or won't even notice, but an improvement is an improvement, whatever brings it closer to the unreachable state of perfection, it matters.
I suggest reading through all the Tips and Policies before doing active contributions, it might be good for you.

Mountain of work that needs doing. Have fun.
