I really don’t see this as a Meta issue. If you don’t feel comfortable doing so, you shouldn’t. It’s solely up to you but you should be able to trust the campaign manager you’re applying to. Back when Bestchange signature campaign was active and one of the biggest campaigns on the forum, their selection process often took longer than two weeks to pick a new participant to join their campaign. A lot of users didn’t seem to mind wearing the avatar and signature during this waiting period. I personally don’t mind wearing the avatar and signature of a company I intend on working with for as long as I’m not currently working in a campaign.r
