Changes in life happen. Nobody can expect a Charter not to take a break.
Dead links can´t be avoided, except maybe if the site would make a backup of every cDLC submitted.
But I guess that would go against their careful policy.
The best way to recover a dead link :
1. Check when the Charter was last online (float mouse pointer above his name). If he was recently, private message him. (friendly)
(sometimes a simple comment on his page is not notified to him)
2. If he's away for too long, do a little spying and identify
- who follows the cDLC
- who likes the cDLC
- who thanked the Charter on the Forum page of the cDLC (I never understood why there are 2 variations of a cDLC page)
Chances are some still have a version, we like to collect, just in case...
PM an identified User, preferably a Magna Charter, (politely)
they know best how to re-upload the song temporarily, until the Charter is back.
I think that's how a Community works
