Enable the log in screen to remember what link was trying to be accessed and direct the user there after they have logged in, instead of always directing them to the WorldShare home page.
If I am not already logged in to my WorldShare/Community Center account when clicking on a link (from an email or from the OCLC website), the sign in screen redirects me to the WorldShare home page no matter what the link was pointing to. This means I cannot access links from emails with a single click, which is just enough of a hassle to discourage clicking through unless I'm very interested in the topic.
Click the link, sign in, then go back to the original link (email/webpage) and click it again so that it actually takes me to where I'm trying to get.
