Removing content from the click through page might make it easier for visitors to find the link to skip it, but it won't help visitors find you in search engines. In the search engine's view a second home page is counterproductive. A page named Home that is not the default is confusing. To compound the issue, your main page and your home page are similar; more than a third of the text is duplicated. Both are light on textual content, and search engines need text to sort things out.
What can you do to help the search engine choose which of your pages to index? Each one should have a unique purpose and adequate text content to tell the search engine why, of all the millions of pages, that one should be indexed. For most people, the purpose of an intro page is a game to find the exit as quickly as possible, click away and get on with business.
If two pages serve the same purpose, then choose one, merge the content, and delete the other before it gets indexed. If one kept pages with duplicate or indistinct content, the search engine would choose between them, and it might exclude the preferred one.
Instead of pictures of generic faces, why not let a photo of your members greet visitors?
Internal navigation is another way to tell the world which of your pages is important and why. Suppose other sites will link to yours, shall we assume that they will link to the default (now splash) page? They commonly do. This is what gives the default page some rank with the search engine. If you leave off navigation and instead have one link on that main page that goes to a single page on your site, all the rest of the pages will rank low. This would reduce your traffic. But if you put navigation on the main page, bestowing links to a few important pages, they would get some traffic.
