Discussion forum design: pattern-based and mobile-based

I would like to develop a small web-based and a mobile device-based discussion forum board. I'am collecting pattern for each of the following design process:

1. Set of requirements (patterns of requirements ellicitation)
2. User interface design (patterns of requirements user interface)
3. Architecture design (patterns of Architecture design)
4. Technological choices (patterns of Technological choices)
5. Implementation (patterns of Implementation)
6. Validation (patterns of sofware validation)
7. Deployment (patterns of sofware Deployment)
8. Evololution (patterns of sofware evololution)

Do you know any reference that could help me find 2 or 3 pattern for each steps? Thanks.
