I just installed bbpress yetserday on a new domain and have integrated it with wordpress using the plugin, etc. I also have found that the default template has no blockquote support. Even by including the blockquote definition given above by Trent verbatim in my bb-admin/style.css file does no good, here is a view source excerpt of the source file:
<blockquote><p>[Shakir 5:57] O you who believe! do not take for guardians those who take your religion for a mockery and a joke...</p></blockquote>
as a test…
testing blockquote here in bbpress support
nope. above line doesnt render in blockquoted indent either.
i think the problem is the insertion of <p></p> tags around every paragraph. Since blockquote is an inline style, the p tags override it. we could get around this by using a div class=blockquote kind of construction instead but wouldt it be nicer if blockquote just worked out of the box?
