Things to Know

This code is not yet written.
We are using a blogging tool that is tiny, reliable, and (I expect) secure. It probably still has bugs. Hollis has checked it, but heaven knows 150 monkeys typing on keyboards in 10 different browsers can make many things happen. Bug reports go to Hollis who will sort, reduce, and funnel them to the development team.
On WYSIWYG authoring in a web browser
Ha! That interface was surely written by children and tested by no one. The blogging tool takes the approach that it is your browser's problem if it doesn't do a decent job. I think IE, Firefox, and webkit based browsers all work, but sometimes it can get a bit maddening if say you are at the end of post and are stuck in bold mode. Try clicking things. Some of the browsers toggle modes, some don't. (When it works it is pretty cool. I can drag URLs into an article and get the title as the text of the link. You may not be able to do that. There is always HTML mode if you need it.)
On Script Injection Attacks
You will probably get an error about illegal content at sometime while posting. It means you (or your lying browser) used a tag or attribute that is not allowed. Usually it is ok to have stripped it. Check the content and proceed.
