I have activated compression on all the website pages, this should make the pages load a bit faster. Most notable change I think is on the members page, which goes from ~150kb to ~21kb size.

The Study area still uses a lot of data that is not compressed so you won't see a big difference there, I'm working on it (hence "part1" ;)).

UPDATE Did more optimization on the pages, using compression on stylesheets and javascripts, plus setting "expire" header on those files. The typical Study page was ~250kb after a full page refresh, now it is ~80kb. The browser should be able to cache the pages more often.
