Hi, Darlene --
The voting site is at https://www.alavote.org/2013/login.aspx. ALA doesn't link directly to the URL because you get a super secret login via email that's different from your ala.org login. Sometime between March 19-21, you should have received an email at the address on your member record with that super secret login information. You may have to check your spam/junk folder to make sure it didn't end up there.
Or, you can use the "Email my login information" link on the voting site to re-send it, although if it went to spam the first time, it's likely to do so the second time, so keep an eye out for it.
Hope this helps, but don't hesitate to ask further questions.
Jenny
