The Digital Research Tools wiki has a nice collection of links to various software tools and resources for different types of research. I like that it is organised around different tasks, and it also seems to have some crosslinks between the different sections.
I had to set up some tables for our wiki, and came across a HTML-to-wiki converter which seems to work well. This makes it possible to create more complex tables in a WYSIWYG HTML editor (e.g. Dreamweaver) and then convert them to wiki markup afterwards.
We have set up a new wiki for the fourMs lab. It is mainly intended as a place for tutorials and various tricks and tips in using the software and hardware systems available. Hopefully, the wiki can also be useful for other researchers in the field.
