Maybe not an issue but the following things should be taken care of:
There are very spiderable links and if it doesn't index well,
let me know what I can do to make it better
I've been meaning to ping you about this for a while - it needs a single canonical URL for each page.
Either //railodocs.org/ or //railodocs.org/functions/ (not both)
Whichever of those is used, the other version should permanent redirect to that URL, as should all other URLs that show the same content (i.e. /index.cfm/function/ and any others)
When the latest current version is in the URL, temporary redirect to the versionless one (until the next release becomes current, then the new latest one gets the temp redirect instead)
When viewing an old versioned page, it should display that version prominently (currently there's no indication other than the URL), along with a "latest version" link to the above current URL - so it's obvious and useful for users, and also ensures the content is not identical (so search engines treat it appropriately).
Oh, and it looks like all the page titles are "Railo Documentation" - should be " - Railo v Documentation" or similar.
Hopefully all this makes sense, but it's been a long day so let me know if anything doesn't.
