You are welcome to edit pages in this wiki, but please enter your name on your "Preferences" page by clicking this link: Edit Preferences
There is no formal "account creation" required. Note, however, that the name you enter on the "Preferences" page must be all one word in "MixedCase" or you will get an invalid username error. So "JimbobMcCranston" is ok, but "Jimbob McCranston" and "jimbob" are not.
The main reason for requiring a name to be set in the preferences is to reduce the amount of spam that has been put into this wiki by spam bots.
If you plan to contribute frequently (or even infrequently), you are invited to create your own homepage here.
