Might want to make an ongoing calendar spreadsheet with details of each sig campaign on it and then mark on it paid or unpaid pending etc and colour code them and have as a progressing calendar. Just my 2 cent to better show status of each one and things can be cross checked with each campaign going to update records and for members to make their decisions on what ones to use etc.
I have been thinking about doing that, but it costs a lot of time to do (which I don't have at the moment). Nice update! Do any signature ad campaigns accept negative trust accounts?
Every signature campaign that I added or updated didn't accept negative trust accounts, so I doubt it.
