Oops! Look what I started ... It does occur to me that if you want to do this, there's an even better way, which would be familiar to anyone trying to deal with the garbage HTML that is generated by a lot of software. Just send an HTML doc with a lot of spurious <font>...</font> or <dir>...</dir> tags. Nobody would ever expect this to contain hidden text, because there is so much of this sort of junk around already. You could also add a whole lot of unnecessary chars here and there. Just put a spurious <META...FrontPage...> tag at the beginning, and nobody would be able to convict you of anything. You wouldn't even have to worry about inserting the tags in legal spots, since FrontPage doesn't. In fact, it'd be better if you could arrange for a few extra </font> and </dir> tags now and then, to make it look like real FrontPage output. The CIA doesn't stand a chance with Microsoft helping us like this. (Bash, bash ... ;-) To subscribe/unsubscribe, point your browser to: http://www.tullochgorm.com/lists.html
