Nuclues is a great system, but some things aren't the way (I think) they should be. This is how I want it:
/
or /directoryname/
/archives/
for the archives index. /archives/2003/
for a overview of a year. /archives/2003/08/
for the overview of a month. /archives/2003/08/04/
for the overview of a day and /arvchives/2003/08/04/featurerequest/
for a specific post. The last keyword should have no caps and should be a simplified title of the post it refers to.
/categories/
for the categories index. /categories/categoryname/
for the overview of a specific category.
That's all!
I have tried something of this sort over at http://wannalookgood.com.
The trouble is ofcourse the fact that as of now, it doesnt support all possible scenarios in which a link can come. One of these days, I am going to finish that plugin so that it supports everything and works smoothly. Keep checking the forum.
