Ok from looks of it this place is still cluttered with some articles, some maybe useless, but possible we can salvage them and turn them into real articles, second any articles we cannot salvage, we can just delete, next, we need to get the users of this wiki back, we message them on other wikis, ask them if they wish to visit or come back here, if they refuse, thats ok, just keep trying if you can or leave them be and continue on finding users who love to RP, and invite them onto this wiki
Now when approching a user who left this wiki, just say these simple words "Hey, some of us are thinking of reviving The Online RPG Wiki, care to join us and revive the wiki?" After that, wait for them to answer, if they answer yes, then thats good, if they answer no or maybe, keep on trying, till you can't do it any longer and just move onto the next user.
I will come up  with some more ideas, any other active Administrators on here, if you wish, we all should meet on this Wiki's Wiki Chat or on another, its your choice. hopefully we can all come up with some ideas to save this wiki.
