A client of mine wanted mailings, donation opportunities (as in receiving), contact all baked into one solution. He was told of CiviCRM.
I downloaded the plugin and tested it out. It is not a part of the WordPress repository as one will need to manually download the WordPress plugin. The UI is older but it works.
I tested the mailing function for my client and it works nicely.
What the CiviCRM guys need is help to get the plugin off the ground.
It seems they need help to get the code correct to get it into the repository, create a better looking UI and whatever else. Tips/advice etc.
