Website is vague on contributing

[Anan-Saadi]

the current landing page is quite confusing when it comes to data contributing, its unclear what is the difference between "join us" and "login" buttons, and the fact there is no mention of contributing to data collection and classification at all, if I hadn't watched YK's video I would have no idea you could even contribute.

For a start I think we should replace the "join us" element of the website to something like "we need your help" with a quick button for signup and maybe even a full page dedicated for explaining data contributing, basically adding details from YK's video to the website to make it easier for people to reach
