Don't Remake Dead Clans
Dead clans died because of inactivity. If you are foolish enough to remake them, you will soon find out how near impossible it is to do so. The inactive and uninterested members will come back and get bored with the clan once again. Instead, help revive the clans we have at Staredit.net. Make them famous throughout the Battle.net community, and remember the fact that SEN Clans have a permenant source of advertisement, thus showing the inconvience of making new clans.
Don't Make New Clans
Try to avoid making new clans. Sure, there are a few rare exceptions to clans who are doing well and are likely to get a forum here in the future. It is extremely difficult to manage a clan, and you would be doing a better service joining another clan.
