We are attempting to link lists from different sites. Not finding a solutionfor this. Has anyone had experience with this or have recommendations?
What is your goal? If the sites are in the same site collection you can create alinked source using Designer and then display that data on a page.
If you are attempting to aggregrate/roll-up/concatenate these lists then any ofseveral 3rd party add-ons will do it. Be careful in picking one whether or notit will span site-collections.
