I came back here on Bitcointalk from a very long hiatus due to personal reasons. I wanted to start offering again my services such as participating in signature campaigns but I don't know where to start. Can some tell me what are the current qualifications to join some campaign and how/where to get them? Any help will be appreciated. Thank you in advance!
I understand that you are back after a long time so you may not know that you need to be active and merits in the last 120 days etc but you should know "Where to get the signature campaigns"
Being a hero member, you should be aware in which section you would see the signature campaigns and in which section you will find bounties. Nothing changed in that part but your asking this question makes me surprised and i wonder many suspicious things in my mind:

Either this account is hacked or newly bought by someone new to the forum and doesn't have an idea on how things work here.
Has the password been changed for this account? I don't see any notification of this in his profile.
