How you want to vet, or which veteran member you want to ask to do so is completely up to you, some may not want to. If you suggest a method which works we all gain a trusted member, if nothing you suggest works well, then nothing gained, nothing lost. Just so you know, I am not a moderator here, this is only between members who are willing to do so, nothing to do with the forum or its rules. Although, I'd rather you see if there is another veteran who is willing to do so with you. Some members don't like vetting, some do.
