Why Administrator not make clear rules of bitcointalk.org this is main thing must be happen when make a site ?
How clear do you want them than thread? I think new users should be urged to read them upon sign-up though.
I have a question about Bitcointalk signatures, could someone help me? In general, is it allowed for one person to include more than one signature at a time? After reaching "Member" position, we can have unlimited text which allows us to add different signatures from different campaigns. Is this against Bitcointalk rules?
There's no forum rule against it but signature campaigns usually only allow one. You also don't get unlimited space so you probably couldn't fit two of most signatures in.
