Opinionated rambling:
As regards the introduction, I think the second paragraph should be removed entirely as it doesn't seem amazingly relevant to what the site really is. It could go in a subpage somewhere, I suppose. The 'Contributing' section should also be removed entirely, as it's too far down for a supposedly important part of the page, and the remaining introductory paragraph could include the link at the end ('Learn More' or some such). After that, there should be a (fairly prominent) link 'Contact us' (or something like that), resulting in the obsolescence and removal of the bottom section of the page ('Copyright' - which doesn't seem to serve any purpose as no one who visits us understands copyright anyway

). I agree that the 'News' section should be compacted as well. Also, the title (IMSLP / Petrucci Music Library) should a) be made to look nicer (i.e., not just plain text IMHO), and b) should be simplified to
IMSLP(Petrucci Music Library)This would result in less confusion as to what the name of the site is (cf. Jim's thread on the subject a while ago). In summary, the vertical structure of the Main Page would then look like this:
TITLE(little intro with LINKS)
BROWSENEWSAs for the right side of the page, FS should be reduced to 2-3, leaving a bit more room for the recent additions. The top part of the page should see the title moved a bit to the left, and all the languages on the right (where they are on most sites) - easier to see that way. The general objective should be to put just enough relevant stuff on the page, so that no one has to scroll down to find something important.
Actually, now that I'm thinking of it, perhaps we should consider a totally different layout. We could take out the darker colors in the center of the page, move the intro higher, and put the 'Browse' section very prominently to the right of it (it would be the biggest thing on the page). FS would go over to the left, where Browse used to be, probably. I'm not certain where we would put News and Recent Additions, but even so, I think having the Browse section up high is something to seriously consider. What do you think?
(also, have you seen the
other thread about a hypothetical tabbed structure?)
