Forum maintenance

Just cleaned up some spam tags from the taxonomy.

Noticed some tags that could mean the same thing:
'templates'
'theme'
'themes'

and this might be unclear:

'design'
'webdesign'

move to fix this.

What is 'contrib'?

Should 'code example' be given children with specific definitions?

Also want to pass the suggestion to think out a proper taxonomy structure in general.

Should we assign a few people to moderate this stuff? Is that technically possible?

Also do we want links to W3C, WCAG, and other official documentation/ validator?

Hope it helps.
