From CCP4 wiki
This [http://www.ccp4.ac.uk/ CCP4] user community wiki ("CCP4 wiki" in short) is meant to be a collection of crystallographic knowledge as discussed on the [http://www.ccp4.ac.uk/ccp4bb.php CCP4 mailing list] (CCP4BB), and elsewhere. It may contain information about anything relevant to protein crystallographers, whether methods-related ("what is the best program for purpose X?"), problem-oriented ("my crystals melt if I look at them"), or concerning hardware ("what is your opinion on robot X / computer Y?").
general [[Topics]] include articles about [[Expression_and_Purification| protein expression and purification]],
[[Crystals| crystal growth, handling and data collection]],[[Crystallography| crystallographic theory and practice]],
and crystal structure related [[Bioinformatics|bioinformatics]] and [[Xtal_computing|computer-related issues]]. There are also announcements for [[Positions|open positions]], [[Courses and Conferences|courses and conferences]] and a [[FAQ|FAQ]].
Many interesting questions are currently being answered on CCP4BB, but the answers are not easily accessible for others after some time. The intention is that the wiki reflect the breadth of topics on CCP4BB, which will make it a useful resource e.g. for "frequently asked questions", offloading some of the question/answer traffic on CCP4BB to a more permanent mode of storage. A wiki has the additional advantage that mathematical formulas and images may be presented nicely.
