Tks, Michael. I'll call to attn of the webmaster. (I'm but one of the users.) The URL is www dot civilwarsignals dot org (note the plural S on signals). As shown below, the "www" was omitted (it is supplied, I believe, by later versions of the Windows software), and I am inserting it with this xmsn. See if that does the trick. [No, it didn't, on Preview. I'll pursue further. Try to enter the URL manually, which works for me, as does my Favorites shortcut.]
Just tried to telephone Mr. Toomey with question about photos -- evidently out of the office.
