The tools are there as Talli described. What I think is the major benefit though of AIMS is the fact that you can make use of these tools using an ASP.
OpenACS & .LRN in my opinion make considerably more sense when taking the whole needs of the NGO into account. They want to communicate with their stakeholders, run an Intranet, keep files safe, easily make content which they have inside their intranet available on the website aso. If you look at this, OpenACS has a lot to offer due to it's capabilities for Campaign (CTK) and Mailing (MLM) Management on the frontend, throw in XCMS (or ETP 😊 ) for public Website, use communities for the Intra-/Extranet and make the Intranet File-Storage available via WebDAV for storing your files on a secure place (assuming you host reliably).
Obviously you could add many more features there, but I just wanted to give you a picture.
