First of all, posting stuff like this is fine, don't worry about that!
Also ... when your article appears in print please feel free to submit a news item. The announcement will then appear on the site's front page in the "news" box (you might want to e-mail me, dave bauer, roberto mello or jeff davis to make sure we notice and approve your news submission).
Also feel free to post a news item if you do attend Exponet.
We should probably get a "press" box up on the home page since more and more people are publishing OpenACS articles etc.
