Actually there's a rule that owners and co-owners are allowed to double post in clubs if they have been inactive for a week or more. ^^ Although the club is currently 3rd in the list, so I don't think there's much to worry about :) Did you contact Xeberos?
Mm, it certainly is a shame when this happens :/ Although it does still seem to get a steady stream of posts which is a relief - I don't think it'll die for quite a while! I think the best thing to do would be to ask the current owner about changes that should be made and tell him your opinion ^^ Clubs are most active when there are interesting and unique topics to discuss; try and get a debate going or a competition so that people have a lot to post about ^^ Or you could even start off a Dawn-based fan fiction which people can build on with each post, that idea has kept certain clubs going for a fair while! Before doing anything though, I suggest you contact the current owner and compare ideas with him. :) Also you could try checking out the Daily Chit-Chat thread for ideas or even use it to ask for some, many people will have similar problems that need solving and this place works best as a community. ^^
