I should be able to pull a quick report to find our current donors based on level, but the results are not accurate. I believe they are pulling from funds that it shouldn't (such as elevated events and donated tickets). I'm looking for advice on how best to set up our membership levels so that when I'm asked how many members we have at a certain level I can easily report on that.
Thanks for the replies everyone, will take a better look at the funds/campaigns. I'm also having issue with dates - the membership not turning off properly even after the previous gift is over two years old. Will definitely have to read up a bit on this. Most of my experience in Tessi has been on the ticketing side, not development.
Your issue with memberships not expiring properly may have to do with the Membership Update Utility not running. This report needs to be scheduled to run regularly--we do it nightly. If you don't have it scheduled, or if your report server isn't working, that might be the issue there.
