Right now the forums are a tad inhospitable, but when things cool down you should definitely make a sidebar on the entry page or something so people can find this wonderful place. When I first went to it, it took me a while to find the forums because I didn't notice the scroll bar. It might happen to ohers as well.
Hmm really? First day i bought this i went to uberent.com and in about 5 minutes went to the forums... maybe i went in inadvertantly looking for the forums which is how i saw it, i'm not sure. Maybe something like the "buy now" box banner would do? It wasn't a problem for me, but if it could be seen as one then by all means, advertise it more. This place makes me laugh all day urr day.
For those that don't know there is a new homepage (which only seems to work when I use the url and not my bookmarks) have a look and see: http://uberent.com Forums and Twitter links are on the very bottom of the page.
