I think usernames are a max of 20 characters, up from 15 a few months back.

Can't speak to usernames though. On Tue, Jun 30, 2009 at 17:39, Scott Haneda <talkli...@newgeo.com> wrote: Awesome, thanks. I found I had to use a "B", so this works form me: \B@([A-Za-z0-9_]+) Word boundary is indeed very handy, works perfect, and the hash tag one works close enough. I know there are limits on length, what are they for both hash tags and @usersnames?

For hashtags I use a similar one: \b#([A-Za-z0-9_-]+) I don't think #foo/bar is a valid hashtag, so I don't account for those. -- Scott * If you contact me off list replace talklists@ with scott@ * -- Internets.
