Being assumptive that I am looking at CKEditor and BBCode as the format of choice for posts, do we have a list anywhere of allowed features and tags ? For example, I can see that (or at least I can't find) a functional set of table tags, for layouts within a post. I would also like to use anchors ? i.e. [goto=A Title]This[/goto] title is also a link within the post. Here is some more text. [anchor]A Title[/anchor] As you can see the output is not parsed, but simply output - leading me to think its not an enabled tag. However I guess you are running a strict filter on post formats ? Do we have anything like markdown, or a limited html set available to us ?
