Issues with categories 
...The convention is to use only initial caps, but there will be many exceptions and good reasons for making them. Somtimes, not establishing a convention will cause redundancy or confusion but will contribute to Wikiversities relaxed atmosphere.
A few examples:
- Category:Computer science - Category:Computer Science
- Category:Bloom Clock Project Plants - Category:Bloom clock project plants (Note: these were intentionally made redundant, for maintenance reasons. see the text on Category:Bloom clock project plants for details).
- Category:Life Sciences - Category:Life sciences
Merging redundant categories 
As SB_Johnny points out, there is a good reason for having both Category:Bloom Clock Project Plants and Category:Bloom clock project plants, and there may be other situations for some seemingly redundant categories such as Category:Schools and Category:Wikiversity schools. Please discuss plans for this week's category sweep at Wikiversity talk:Categories/2007/Week22.
