For a signature campaign manager, they hold the funds, and manage participants? Any recommendations for one?
If you don't want to deal with the frustrations that come with running a signature campaign, I strongly advise you to hire a reputable manager to handle it for you. @Lordhermes have already given you a link to the
topic where you can find a good manager. Additionally, in
Services section you can find the individual topics of most active managers where you can see a portfolio of their current and past campaigns.
I don't want to single out anyone in particular; all I can say is that the
campaign manager with whom I am currently working will do his job professionally and courteously.
I see that most of the current signature campaigns on the main thread are only open for higher level members. Is this open for our decision to decide which levels will be eligible?
You have complete control over who you recruit for your campaign. Just keep in mind that signature limits vary by forum rank. As a result, as @SFR10 previously indicated, members with a forum rank below the Member rank are unable to carry active links in their signatures.
I suggest that you discuss these and other technical details with your chosen manager, as he is much more familiar with the subject.
Good luck in your future endeavors.
