It’s buggy and irritating (I’m talking about the Groups web site). Joining is totally borked if you don’t already have a Yahoo! account, and the “tell the moderator why you want to join” has a 200-character limit on the message you send. Only, the Yahoo! web devs are so stupid that they didn’t put a live character count on the text box, so it’s a guessing game to figure out if your text is short enough – or you have to manually count the letters yourself. Give me a break. Idiots. No wonder they’re an almost-ran to Google.
