Quotes llama

I've found some bug (report in forum) and, also, i cannot found a simple way to link directly a quote (or a author list).
If i click in gallery list i can go to letter and filter by author, but when i click hover an author i've url like this: #quotes-llama-page-print
then, no name, nothing to link.
then, i cannot share, i don't have an rss, i cannot link.
also, use deprecated code (first of all, clear="..." in html instead of css).
so, can be a good plugin, but, i repeat, this need optimization and fix :)



Good style, but need some optimization

Was looking for a new plugin after quotes collection.
This one works perfectly!
