I'm looking to have some WordPress functionality that I don't see available anywhere else. Seems to me that it would be great to do a plugin for it. I think it would actually be extremely easy to write -- for someone who is comfortable with PHP, which I'm not, since I end up spending 15 minutes of research to accomplish even tiny little elementary bits of PHP. Someone knowledgable could probably whip the thing up in less than an hour.
In a nutshell, it would just be a function one could put in a post, specifying a few variables, so that a bit of simple HTML would end up in the post. It's the kind of thing that might be usable by a lot of people, so it could get you some attention. Anyone interested?
