Another short tip on a site that is remarkably hard to find but very handy: Wikimatrix. I often use wiki’s to store information and short notes to be able to find things back quickly. As always the problem is what wiki software to run. There are literally thousands of options.
On Wikimatrix.org they offer a wizard which will help to narrow down to choices. Besides you can side-by-side compare different wiki’s. Not all wiki’s are that good though ( keep in mind ) but this site will help to narrow down your search.
