Since you are an unofficial clan pretty much nothing is gonna happen. Clan staff doesnt do activity checks for unofficial clans, so you, unless you actually close the thread down, leave the clan etc etc, it wont "die".
As for tips, you might want to go ingame, try to make some recruiting servers, get some people interested in your clan. Leading a clan isnt the easiest thing to do so don't worry if it doesn't go as well as planned right away.
