Regarding code disappearing, it may be due to editing in visual mode. There are several similar forum postings that discuss this issue. Here is a link. I think you may be editing your post using the visual editor, and then wordpress strips the tags.
hi jc62! Thanks for the info, however, I do edit in the HTML mode, and still the <blink></blink> code disappears after I hit post. 🙁
Hmm, interesting… I had an odd issue about a year ago where the visual/html editor was not acting normal. It turned out to be a plugin that had nothing to do with editing.
If you have admin access, I would recommend disabling all plugins, and test. If the editing works ok, then turn on one plugin at a time to see which one creates the problem.
BTW: the <blink> tag by itself is not supported by most browsers. When reviewing a few pages on the referenced site it appears the html tag is not actually performing the blinking. I think there is some javascript/jquery that implements this feature.
