Just thought I'd point out, when you sign-up to T35 free hosting you are advised that the password can be up to 24 characters, but upon entering my longer than 16 character password it was truncated to 16 characters.

However, I was able to subsequently change it to longer than 16 via the http://www.t35.com/memarea/ page so it just looks like a quirk on the sign-up process.
