If I can remember, the last signature campaign I tracked myself to that I first joined is Rollbit, but I think I have joined some campaigns before I joined Rollbit. I could not remember if I have joined a signature campaign before or not before Rollbit.
Is there anyway someone can track all the signature campaigns he has joined before on this forum?
For now there is no that kind of option in bitcointalk forum that will approve you to see that your signature or avatar log. Now there is only one option you can create a topic on service board and save leaving and joining data there by posting.
Besides, Maybe LoyceV has such a signature and Avatar log service, you can find details about it here-
LoyceV's Avatar and Signature log (campaign managers read this!)
