EDIT (5/27/2012): So far, I've gotten up until mission 4/6 filled out, at least in terms of mission descriptions, objectives, and image stuff. Every new mission still needs time and score filled out for S rank, and I know very little about items, particularly because I can't get all of them (I can't really S rank missions by myself, after all...). Tips would also be appreciated, but since I seem to be the only one editing the wiki at the moment, help seems improbable. Ah well.
Over the next couple of days, I'll get the same info for missions 5/1 - 5/6, 6/1, and 6/3. I've taken the liberty of uploading all mission photos, including any cutscene and PVP mission, so feel free to use them (Or replace them with better ones if you can get a good shot) if you want to fill in the missions as well.
Well, with character pages at a standstill due to, well, me not being able to learn any more about skills, I decided to start working on Mission pages. I've got up until 6/3, so expect to see mission pages for those coming up in the next few days.
I'm still unsure if I should make mission pages for all X/7 Missions, since they're nothing more than cutscenes for the most part, but for the sake of completion, I probably will, regardless of how small they'll be. It'd probably be useful to have them just because, really.
I'll need help figuring out times, scores, and rewards, as I don't know them off-hand. Furthermore, if anyone has any tips for missions that currently have none, feel free to fill them in.
