I'd like to be able to import existing HTML pages into Confluence. We have a good sized set of HTML pages that we were using like a Wiki and I'd like to pull the information contained in them into Confluence.
Also, my team member's major complaint about Confluence is the markup; they'd rather use HTML (they may get used to the markup after using it more). It would be a great benefit to allow them to write an HTML page on their local system and then import that into Confluence. This doesn't need to be dynamic, just a simple one-time import after which the data is stored in Confluence's native markup format.
This may be really hard or may already be possible, but it would be a major selling point for my team.
