Thanks to everyone at the Plato workshop yesterday in Dublin. These are the links mentioned, along with a few more:
Open Source software database
Open Source (OS) is free software (sometime you pay if you need more work or adapting for your company). Freshmeat.net is the largest database of OS.
Examples of OS Customer Relationship Systems (CRM which is client databases) include
Tactile has a free CRM program. You don’t need any software, it’s all online. Easy to use.
Sugar is the biggest OS CRM system out there we think. It can be unwieldly and you need to know what you’re doing.
