in that case there was lots to do.. * Your title and your site description is too simple change that so it will look more interesting especially your site description, even though already containing your keyword it's just too simple and boring (they were many site like this already so you have to make yours looks unique) * You also need to work at your page, get rid of the donate thing on your sidebar you can add it later or you can add in the bottom of your sidebar looks ugly to me..sorry * The category..well it seems to me the whole things looks unbalanced with the archive post, i suggest you change that using drop down type/click to learn more and such to listing the category, it will make your site looks nicer and easier to navigate * The archive is good, adding caption is also nice but...the description is horrible, hard to understand you gotta fix that, adding your keyword into archive description is also good just make it simple and easier to understand * Maybe you also need to change your theme into more well brighter...it's too simple, adding some art like wallpapers it's also okay but not too much * Your site is also so heavy to load maybe my connection but the loading is a little slow.. that is what i think about your site, good luck
the new theme, try to look at elegantthemes.com they were not free though or you can try to work out your theme little by little no need to rush doing it..
I added a cache plugin to speed up the page load, as for theme is there a way to seperate sub categories in archive
