Hi Anne--Are you referring to a collection of online professional development resources? I like Symbaloo, but it doesn't give enough information at first glance. You have to click through and hope to find what you want. Its advantage is that it is easily recognized by most users. Another like it though more visual is Padlet which has the advantage of being more fun, more appealing. I use lists on Ask a Tech Teacher for speed of use and function. They are quickly searched and can usually provide necessary information in minutes.

Does that help? Is there one option you were considering?
