I see that there is a lot of knowledge floating on this site. I see sometimes same questions popping up from time to time, lots of site information is out dated and so on.
I would like to request WordPress community to introduce a Wiki where people can share their knowledge and others could edit or complete the subjects other people started, if necessary, in a more structured manner. I believe through the Wiki many others can easier find their answers without wasting too much time searching for unapproved answers.
An important issue could also concern plugin and Theme customizations and tricks. Everything should be gathered in one place.
Please consider this issue ASAP.
