private servers only thrived when eoc came and you couldn't clan on real rs. when 07 came, rsps clanning started going downhill.
only way we'll see rsps clanning come back is if something happens to 07 that makes it impossible to clan, which probably won't happen.
also, rsps clans depended solely on member quality since gear and stats weren't a variable. if it were to come back it would have to be like alotic in terms of how hard the xp rate is and how hard the gear/supplies are to obtain. kids will complain but its the only way to keep things interesting.
