In Confluence 1.4.x the inserted text notation output <ins>inserted text</ins> making it really easy to add styles to inserted text (useful for marking up changes to legal documents, etc). However, in Conf 2.x the same notation seems to output <u>inserted text</u> - as underlined text is used elsewhere it's now rather more difficult to style insertions. Also, it seems a bit of an odd change because deletions still output <del>deletions</del> and it would be nice if the corresponding tag was used for insertions. (Originally raised by Guy Fraser on conf-user list.)
